Write-EventLog

NAME
    Write-EventLog

SYNOPSIS
    Writes an event to an event log.

SYNTAX
    Write-EventLog [-LogName] <string> [-Source] <string> [-EventId] <int> [-Message] <string> [[-EntryType] {Error | Warning | Information | SuccessAudit | FailureAudit}] [-Category <Int16>] [-ComputerName <string>] [-RawData <Byte[]>] [<CommonParameters>]

DESCRIPTION
    The Write-EventLog cmdlet writes an event to an event log.

    To write an event to an event log, the event log must exist on the computer and the source must be registered for the event log.

    The cmdlets that contain the EventLog noun (the EventLog cmdlets) work only on classic event logs. To get events from logs that use the Windows Event Log technology in Windows Vista and later versions of Windows, use Get-WinEvent.

cmdlet, Connection, Test

Test-Connection

NAME
    Test-Connection

SYNOPSIS
    Sends ICMP echo request packets (“pings”) to one or more computers.

SYNTAX
    Test-Connection [-ComputerName] <string[]> [[-Source] <string[]>] [-AsJob] [-Authentication {Default | None | Connect | Call | Packet | PacketIntegrity | PacketPrivacy | Unchanged}] [-BufferSize <int>] [-Count <int>] [-Credential <PSCredential>] [-Delay <int>] [-Impersonation {Default | Anonymous | Identify | Impersonate | Delegate}] [-Quiet] [-ThrottleLimit <int>] [-TimeToLive <int>] [<CommonParameters>]

DESCRIPTION
    The Test-Connection cmdlet sends Internet Control Message Protocol (ICMP) echo request packets (“pings”) to one or more remote computers and returns the echo response replies. You can use this cmdlet to determine whether a particular computer can be contacted across an Internet Protocol (IP) network.

    You can use the parameters of Test-Connection to specify both the sending and receiving computers, to run the command as a background job, to set a timeout and number of pings, and to configure the connection and authentication.

    Unlike the traditional “ping” command, Test-Connection returns a Win32_PingStatus object that you can investigate in Windows PowerShell, but you can use the Quiet parameter to force it to return only a Boolean value.

PARAMETERS
    -AsJob [<SwitchParameter>]
        Runs the command as a background job.

        Note: To use this parameter, the local and remote computers must be configured for remoting and, on Windows Vista and later versions of Windows, you must open Windows PowerShell with the “Run as administrator” option. For more information, see about_remote_requirements.

        When you use the AsJob parameter, the command immediately returns an object that represents the background job. You can continue to work in the session while the job completes. The job is created on the local computer and the results from remote computers are automatically returned to the local computer. To get the job results, use the Receive-Job cmdlet.

        For more information about Windows PowerShell background jobs, see about_jobs and about_remote_Jobs.

    ————————– EXAMPLE 1 ————————–

    C:\PS>Test-Connection server01

    Source        Destination     IPV4Address     IPV6Address Bytes    Time(ms)
    ——        ———–     ———–     ———– —–    ——–

    ADMIN1        Server01        157.59.137.44                32     1

    Description
    ———–
    This command sends echo request packets (“pings”) from the local computer to the Server01 computer. This command uses the ComputerName parameter to specify the Server01 computer, but omits the optional parameter name.

    ————————– EXAMPLE 2 ————————–

    C:\PS>Test-Connection -ComputerName server01, server02, server12 -Credential domain01\user01

    Description
    ———–
    This command sends pings from the local computer to several remote computers. It uses the Credential parameter to specify a user account that has permission to ping all of the remote computers.

    ————————– EXAMPLE 3 ————————–

    C:\PS>Test-Connection -Source Server02, Server 12, localhost -ComputerName Server01

    Description
    ———–
    This command sends pings from different source computers to a single remote computer, Server01. Use this command format to test the latency of connections from multiple points.

    ————————– EXAMPLE 4 ————————–

    C:\PS>Test-Connection -ComputerName Server01 -Count 3 -Delay 2 -TTL 256 -BufferSize 256 -throttle 32

    Description
    ———–
    This command sends three pings from the local computer to the Server01 computer. It uses the parameters of Test-Connection to customize the command.

    Use this command format when the ping response is expected to take longer than usual, either because of an extended number of hops or a high-traffic network condition.

    ————————– EXAMPLE 5 ————————–

    C:\PS>$job = Test-Connection -ComputerName (Get-Content servers.txt) -AsJob

    C:\PS> if ($job.jobstateinfo.state -ne “Running”) {$results = Receive-Job $job}

    Description
    ———–
    This example shows how to run a Test-Connection command as a Windows PowerShell background job.

    The first command uses the Test-Connection cmdlet to ping many computers in an enterprise. The value of ComputerName parameter is a Get-Content command that reads a list of computer names from the Servers.txt file. The command uses the AsJob parameter to run the command as a background job.

    The second command checks to see that the job is not still running, and if it is not, it uses a Receive-Job command to get the results and store them in the $results Variable.

    ————————– EXAMPLE 6 ————————–

    C:\PS>Test-Connection Server55 -Credential domain55\user01 -Impersonation Identify

    Description
    ———–
    This command uses the Test-Connection cmdlet to ping a remote computer. The command uses the Credential parameter to specify a user account with permission to ping the remote computer and the Impersonation parameter to change the impersonation level to “Identify”.

    ————————– EXAMPLE 7 ————————–

    C:\PS>if (Test-Connection -ComputerName Server01 -quiet) {New-PSSession Server01}

    Description
    ———–
    This command creates a PSSession on the Server01 only if at least one of the pings sent to the computer succeeds.

    The command uses the Test-Connection cmdlet to ping the Server01 computer. The command uses the Quiet parameter, which returns a Boolean value, instead of a Win32_PingStatus object. The value is $True if any of the four pings succeed and is, otherwise, false.

    If the Test-Connection command returns a value of $True, the command uses the New-PSSession cmdlet to create the PSSession.

cmdlet, Test, WSMan

Test-WSMan

NAME
    Test-WSMan

SYNOPSIS
    Tests whether the WinRM service is running on a local or remote computer.

SYNTAX
    Test-WSMan [[-ComputerName] <string>] [-Authentication <Authentication>] [-Credential <PSCredential>] [<CommonParameters>]

DESCRIPTION
    The Test-WSMan cmdlet submits an identification request that determines whether the WinRM service is running on a local or remote computer. If the tested computer is running the service, the cmdlet displays the WS-Management identity schema, the protocol version, the product vendor, and the product version of the tested service.

PARAMETERS
    -Authentication <Authentication>
        Specifies the authentication mechanism to be used at the server. Possible values are:
        – Basic: Basic is a scheme in which the user name and password are sent in clear text to the server or proxy.
        – Default : Use the authentication method implemented by the WS-Management protocol.
        – Digest: Digest is a challenge-response scheme that uses a server-specified data string for the challenge.
        – Kerberos: The client computer and the server mutually authenticate by using Kerberos Certificates.
        – Negotiate: Negotiate is a challenge-response scheme that negotiates with the server or proxy to determine the scheme to use for authentication. For example, this parameter value allows negotiation to determine whether the Kerberos protocol or NTLM is used.
        – CredSSP: Use Credential Security Service Provider (CredSSP) authentication, which allows the user to delegate credentials. This option is designed for commands that run on one remote computer but collect data from or run additional commands on other remote computers.

        Caution: CredSSP delegates the user’s credentials from the local computer to a remote computer. This practice increases the security risk of the remote operation. If the remote computer is compromised, when credentials are passed to it, the credentials can be used to control the network session.

        Important: If the authentication parameter is not specified, then the Test-WSMan request will be sent to the remote machine anonymously (without using authentication). If the Test-WSMan request is made anonymously, it does not return any information that is specific to the operating-system version. Instead, Test-WSMan displays null values for the operating system version and service pack level (OS: 0.0.0 SP: 0.0).

        Required?                    false
        Position?                    named
        Default value
        Accept pipeline input?     false
        Accept wildcard characters? false

    -ComputerName <string>
        Specifies the computer against which you want to run the management operation. The value can be a fully qualified domain name, a NetBIOS name, or an IP address. Use the local computer name, use localhost, or use a dot (.) to specify the local computer. The local computer is the default. When the remote computer is in a different domain from the user, you must use a fully qualified domain name must be used.

        Required?                    false
        Position?                    1
        Default value                localhost
        Accept pipeline input?     false
        Accept wildcard characters? false

    -Credential <PSCredential>
        Specifies a user account that has permission to perform this action. The default is the current user. Type a user name, such as “User01”, “Domain01\User01”, or User@Domain.com. Or, enter a PSCredential object, such as one returned by the Get-Credential cmdlet. When you type a user name, you will be prompted for a password.

        Required?                    false
        Position?                    named
        Default value
        Accept pipeline input?     false
        Accept wildcard characters? false

    <CommonParameters>
        This cmdlet supports the common parameters: Verbose, Debug,
        ErrorAction, ErrorVariable, WarningAction, WarningVariable,
        OutBuffer and OutVariable. For more information, type,
        “Get-Help about_CommonParameters“.

INPUTS
    None
        This cmdlet does not accept any input.

OUTPUTS
    None
        This cmdlet does not generate any output object.

NOTES

        By default, the Test-WSMan cmdlet queries the WinRM service without using authentication, and it does not return any information that is specific to the operating-system version. Instead, it displays null values for the operating system version and service pack level (OS: 0.0.0 SP: 0.0).

Set-WSManInstance

NAME
    Set-WSManInstance

SYNOPSIS
    Modifies the management information that is related to a resource.

SYNTAX
    Set-WSManInstance [-ApplicationName <string>] [-ComputerName <string>] [-Fragment <string>] [-Port <int>] [-UseSSL] -ResourceURI <Uri> [[-SelectorSet] <hashtable>] [-Authentication <AuthenticationMechanism>] [-Credential <PSCredential>] [-Dialect <Uri>] [-FilePath <File>] [-SessionOption <hashtable>] [-ValueSet <hashtable>] [<CommonParameters>]

    Set-WSManInstance [-ConnectionURI <Uri>] [-Fragment <string>] -ResourceURI <Uri> [[-SelectorSet] <hashtable>] [-Authentication <AuthenticationMechanism>] [-Credential <PSCredential>] [-Dialect <Uri>] [-FilePath <File>] [-SessionOption <hashtable>] [-ValueSet <hashtable>] [<CommonParameters>]

DESCRIPTION
    The Set-WSManInstance cmdlet modifies the management information that is related to a resource.

    This cmdlet uses the WinRM connection/transport layer to modify the information.

PARAMETERS
    -ApplicationName <string>
        Specifies the application name in the connection. The default value of the ApplicationName parameter is “WSMAN”. The complete identifier for the remote endpoint is in the following format:

             <transport>://<server>:<port>/<ApplicationName>

        For example:

             http://server01:8080/WSMAN

        Internet Information Services (IIS), which hosts the session, forwards requests with this endpoint to the specified application. This default setting of “WSMAN” is appropriate for most uses. This parameter is designed to be used when numerous computers establish remote connections to one computer that is running Windows PowerShell. In this case, IIS hosts Web Services for Management (WS-Management ) for efficiency.

        Required?                    false
        Position?                    named
        Default value                WSMan
        Accept pipeline input?     false
        Accept wildcard characters? false

    -Authentication <AuthenticationMechanism>
        Specifies the authentication mechanism to be used at the server. Possible values are:

        – Basic: Basic is a scheme in which the user name and password are sent in clear text to the server or proxy.
        – Default : Use the authentication method implemented by the WS-Management protocol. This is the default.
        – Digest: Digest is a challenge-response scheme that uses a server-specified data string for the challenge.
        – Kerberos: The client computer and the server mutually authenticate by using Kerberos Certificates.
        – Negotiate: Negotiate is a challenge-response scheme that negotiates with the server or proxy to determine the scheme to use for authentication. For example, this parameter value allows negotiation to determine whether the Kerberos protocol or NTLM is used.
        – CredSSP: Use Credential Security Service Provider (CredSSP) authentication, which allows the user to delegate credentials. This option is designed for commands that run on one remote computer but collect data from or run additional commands on other remote computers.

        Caution: CredSSP delegates the user’s credentials from the local computer to a remote computer. This practice increases the security risk of the remote operation. If the remote computer is compromised, when credentials are passed to it, the credentials can be used to control the network session.

        Required?                    false
        Position?                    named
        Default value
        Accept pipeline input?     false
        Accept wildcard characters? false

    -ComputerName <string>
        Specifies the computer against which you want to run the management operation. The value can be a fully qualified domain name, a NetBIOS name, or an IP address. Use the local computer name, use localhost, or use a dot (.) to specify the local computer. The local computer is the default. When the remote computer is in a different domain from the user, you must use a fully qualified domain name must be used. You can pipe a value for this parameter to the cmdlet.

        Required?                    false
        Position?                    named
        Default value                localhost
        Accept pipeline input?     false
        Accept wildcard characters? false

    -ConnectionURI <Uri>
        Specifies the connection endpoint. The format of this string is:

             <Transport>://<Server>:<Port>/<ApplicationName>

        The following string is a properly formatted value for this parameter:

    -Credential <PSCredential>
        Specifies a user account that has permission to perform this action. The default is the current user. Type a user name, such as “User01”, “Domain01\User01”, or “User@Domain.com”. Or, enter a PSCredential object, such as one returned by the Get-Credential cmdlet. When you type a user name, you will be prompted for a password.

        Required?                    false
        Position?                    named
        Default value
        Accept pipeline input?     false
        Accept wildcard characters? false

    -Dialect <Uri>
        Specifies the dialect to use in the filter predicate. This can be any dialect that is supported by the remote service. The following Aliases can be used for the dialect URI:

        – WQL: http://schemas.microsoft.com/wbem/wsman/1/WQL
        – Selector: http://schemas.microsoft.com/wbem/wsman/1/wsman/SelectorFilter
        – Association: http://schemas.dmtf.org/wbem/wsman/1/cimbinding/associationFilter

        Required?                    false

        Accept pipeline input?     false
        Accept wildcard characters? false

    -FilePath <File>
        Specifies the path of a file that is used to update a management resource. You specify the management resource by using the ResourceURI parameter and the SelectorSet parameter . For example, the following command uses the FilePath parameter:

        Invoke-WSManAction -action stopservice -ResourceURI wmicimv2/Win32_Service -SelectorSet @{Name=”spooler”} -FilePath:c:\input.xml -Authentication default

        This command calls the StopService method on the Spooler service by using input from a file. The file, Input.xml, contains the following content:

        <p:StopService_INPUT xmlns:p=”http://schemas.microsoft.com/wbem/wsman/1/wmi/root/cimv2/Win32_Service”/>

        Required?                    false
        Position?                    named
        Default value
        Accept pipeline input?     true (ByPropertyName)

        Specifies a section inside the instance that is to be updated or retrieved for the specified operation. For example, to get the status of a spooler service, specify “-Fragment Status”.

        Required?                    false
        Position?                    named
        Default value
        Accept pipeline input?     false
        Accept wildcard characters? false

    -OptionSet <hashtable>
        Passes a set of switches to a service to modify or refine the nature of the request. These are similar to switches used in command-line shells because they are service specific. Any number of options can be specified.

        The following example demonstrates the syntax that passes the values 1, 2, and 3 for the a, b, and c parameters:

             -OptionSet @{a=1;b=2;c=3}

        Required?
        Position?                    named
        Default value
        Accept pipeline input?     false
        Accept wildcard characters? false

    -Port <int>
        Specifies the port to use when the client connects to the WinRM service. When the transport is HTTP, the default port is 80. When the transport is HTTPS, the default port is 443. When you use HTTPS as the transport, the value of the ComputerName parameter must match the server’s Certificate common name (CN). However, if the SkipCNCheck parameter is specified as part of the SessionOption parameter, then the Certificate common name of the server does not have to match the host name of the server. The SkipCNCheck parameter should be used only for trusted machines.

        Required?                    false
        Position?                    named
        Default value
        Accept pipeline input?     false

        Accept pipeline input?     false
        Accept wildcard characters? false

    -SelectorSet <hashtable>
        Specifies a set of value pairs that are used to select particular management resource instances. The SelectorSet parameter is used when more than one instance of the resource exists. The value of the SelectorSet parameter must be a hash table. The following example shows how to enter a value for this parameter:

            -SelectorSet @{Name=”WinRM”;ID=”yyy”}

        Required?                    false
        Position?                    2
        Default value
        Accept pipeline input?     true (ByValue, ByPropertyName)

Show-EventLog

NAME
    Show-EventLog

SYNOPSIS
    Displays the event logs of the local or a remote computer in Event Viewer.

SYNTAX
    Show-EventLog [[-ComputerName] <string>] [<CommonParameters>]

DESCRIPTION
    The Show-EventLog cmdlet opens Event Viewer on the local computer and displays in it all of the classic event logs on the local computer or a remote computer.

    To open Event Viewer on Windows Vista and later versions of Windows, the current user must be a member of the Administrators group on the local computer.

    The cmdlets that contain the EventLog noun (the EventLog cmdlets) work only on classic event logs. To get events from logs that use the Windows Event Log technology in Windows Vista and later versions of Windows, use Get-WinEvent.

PARAMETERS
    -ComputerName <string>
        Specifies a remote computer. Show-EventLog displays the event logs from the specified computer in Event Viewer on the local computer. The default is the local computer.

        Type the NetBIOS name, an Internet Protocol (IP) address, or a fully qualified domain name of a remote computer.

        This parameter does not rely on Windows PowerShell remoting. You can use the ComputerName parameter of Get-EventLog even if your computer is not configured to run remote commands.

        Required?                    false
        Position?                    1
        Default value                .
        Accept pipeline input?     false
        Accept wildcard characters? false

    <CommonParameters>
        This cmdlet supports the common parameters: Verbose, Debug,
        ErrorAction, ErrorVariable, WarningAction, WarningVariable,
        OutBuffer and OutVariable. For more information, type,
        “Get-Help about_CommonParameters“.

INPUTS
    None
        You cannot pipe input to this cmdlet.

OUTPUTS
    None
        This cmdlet does not generate any output.

NOTES

        The Windows PowerShell command prompt returns as soon as Event Viewer opens. You can work in the current session while Event Viewer is open.

        Because this cmdlet requires a user interface, it does not work on Server Core installations of Windows Server.

Stop-Computer

NAME
    Stop-Computer

SYNOPSIS
    Stops (shuts down) local and remote computers.

SYNTAX
    Stop-Computer [[-ComputerName] <string[]>] [[-Credential] <PSCredential>] [-AsJob] [-Authentication {Default | None | Connect | Call | Packet | PacketIntegrity | PacketPrivacy | Unchanged}] [-Force] [-Impersonation {Default | Anonymous | Identify | Impersonate | Delegate}] [-ThrottleLimit <int>] [-Confirm] [-WhatIf] [<CommonParameters>]

DESCRIPTION
    The Stop-Computer cmdlet shuts down computers remotely. It can also shut down the local computer.

    You can use the parameters of Stop-Computer to run the shutdown operations as a background job, to specify the authentication levels and alternate credentials, to limit the concurrent connections that are created to run the command, and to force an immediate shut down.

    This cmdlet does not require Windows PowerShell remoting unless you use the AsJob parameter.

PARAMETERS
    -AsJob [<SwitchParameter>]
        Runs the command as a background job.

        Note: To use this parameter, the local and remote computers must be configured for remoting and, on Windows Vista and later versions of Windows, you must open Windows PowerShell with the “Run as administrator” option. For more information, see about_remote_requirements“.

        When you use the AsJob parameter, the command immediately returns an object that represents the background job. You can continue to work in the session while the job completes. The job is created on the local computer and the results from remote computers are automatically returned to the local computer. To manage the job, use the Job cmdlets. To get the job results, use the Receive-Job cmdlet.

        For more information about Windows PowerShell background jobs, see about_jobs and see about_remote_Jobs.

        You cannot pipe input to this cmdlet.

OUTPUTS
    None or System.Management.Automation.RemotingJob
        When you use the AsJob parameter, the cmdlet returns a job object (System.Management.Automation.RemotingJob). Otherwise, it does not generate any output.

NOTES

        This cmdlet uses the Win32Shutdown method of the Win32_OperatingSystem WMI class.

    ————————– EXAMPLE 1 ————————–

    C:\PS>Stop-Computer

    Description
    ———–
    This command shuts down the local computer.

    ————————– EXAMPLE 2 ————————–

    C:\PS>Stop-Computer -ComputerName Server01, Server02, localhost

    Description
    ———–
    This command stops two remote computers, Server01 and Server02, and the local computer, identified as “localhost”.

    ————————– EXAMPLE 3 ————————–

    C:\PS>$j = Stop-Computer -ComputerName Server01, Server02 -AsJob

    C:\PS> $results = $j | Receive-Job

    C:\PS> $results

    Description
    ———–
    These commands run a Stop-Computer command as a background job on two remote computers, and then get the results.

    The first command uses the AsJob parameter to run the command as a background job. The command saves the resulting job object in the $j Variable.

    The second command uses a pipeline operator to send the job object in $j to the Receive-Job cmdlet, which gets the job results. The command saves the results in the $results Variable.

    The third command displays the result saved in the $results Variable.

    Because the AsJob parameter creates the job on the local computer and automatically returns the results to the local computer, you can run the Receive-Job command as a local command.

    ————————– EXAMPLE 4 ————————–

    C:\PS>Stop-Computer -comp Server01 -Impersonation anonymous -Authentication PacketIntegrity

    Description
    ———–
    This command restarts the Server01 remote computer. The command uses customized impersonation and authentication settings.

    ————————– EXAMPLE 5 ————————–

    C:\PS>$s = Get-Content domain01.txt

    C:\PS> $c = Get-Credential domain01\admin01

    C:\PS> Stop-Computer -ComputerName $s -Force -ThrottleLimit 10 -Credential $c

    Description
    ———–
    These commands force an immediate shut down of all of the computers in Domain01.

    The first command gets a list of computers in the domain and saves it in the $s Variable.

    The second command gets the credentials of a domain administrator and saves them in the $c Variable.

    The third command shuts down the computers. It uses ComputerName parameter to submit the list of computers in the $s Variable, the Force parameter to force an immediate shutdown, and the Credential parameter to submit the credentials saved in the $c Variable. It also uses the ThrottleLimit parameter to limit the command to 10 concurrent connections.

    ————————– EXAMPLE 1 ————————–

    C:\PS>Set-Service -Name lanmanworkstation -DisplayName “LanMan Workstation”

    Description
    ———–
    This command changes the display name of the lanmanworkstation service to “LanMan Workstation”. (The default is “Workstation”.)

    ————————– EXAMPLE 2 ————————–

    C:\PS>Get-WmiObject win32_service -filter “name = ‘SysmonLog'”

    ExitCode : 0
    Name     : SysmonLog
    ProcessId : 0
    StartMode : Manual
    State     : Stopped
    Status    : OK

    C:\PS> Set-Service sysmonlog -StartupType automatic

    C:\PS> Get-WmiObject win32_service -filter “name = ‘SysmonLog'”

    ExitCode : 0
    Name     : SysmonLog

    AdtAgent                             Auto
    Alerter                             Disabled
    ALG                                 Manual
    AppMgmt                             Manual
    …

    Description
    ———–
    These commands get the startup type of the Performance Logs and Alerts (SysmonLog) service, set the start mode to automatic, and then display the result of the change.

    These commands use the Get-WmiObject cmdlet to get the Win32_Service object for the service, because the ServiceController object that Get-Service returns does not include the start mode.

    The first command uses the Get-WmiObject cmdlet to get the Windows Management Instrumentation (WMI) object that represents the SysmonLog service. The default output of this command displays the start mode of the service.

    The second command uses Set-Service to change the start mode to automatic. Then, the first command is repeated to display the change.

    The final command displays the start mode of all services on the computer.

    ————————– EXAMPLE 3 ————————–

    C:\PS>Set-Service -Name Schedule -ComputerName S1 -Description “Configures and schedules tasks.”

    C:\PS> Get-WmiObject win32_service -ComputerName s1 | Where-Object {$_.Name -eq “Schedule”} | Format-List Name, Description

    Description
    ———–
    These commands change the description of the Task Scheduler service on the S1 remote computer and then display the result.

    These commands use the Get-WmiObject cmdlet to get the Win32_Service object for the service, because the ServiceController object that Get-Service returns does not include the service description.

    The first command uses a Set-Service command to change the description. It identifies the service by using the service name of the service, “Schedule”.

    The second command uses the Get-WmiObject cmdlet to get an instance of the WMI Win32_Service that represents the Task Scheduler service. The first element in the command gets all instances of the Win32_service class.

    The pipeline operator (|) passes the result to the Where-Object cmdlet, which selects instances with a value of “Schedule” in the Name property.

    Another pipeline operator sends the result to the Format-List cmdlet, which formats the output as a list with only the Name and Description properties.

    ————————– EXAMPLE 4 ————————–

    C:\PS>Set-Service winrm -Status Running -PassThru -ComputerName Server02

    Description
    ———–
    This command starts the WinRM service on the Server02 computer. The command uses the Status parameter to specify the desired status (“running”) and the PassThru parameter to direct Set-Service to return an object that represents the WinRM service.

    ————————– EXAMPLE 5 ————————–

    C:\PS>Get-Service schedule -ComputerName S1, S2 | Set-Service -Status paused

    Description
    ———–
    This command suspends the Schedule service on the S1 and S2 remote computers. It uses the Get-Service cmdlet to get the service. A pipeline operator (|) sends the service to the Set-Service cmdlet, which changes its status to “Paused”.

    ————————– EXAMPLE 6 ————————–

    C:\PS>$s = Get-Service schedule

    C:\PS> Set-Service -inputobject $s -Status stopped

    Description
    ———–
    These commands stop the Schedule service on the local computer.

    The first command uses the Get-Service cmdlet to get the Schedule service. The command saves the service in the $s Variable.

    The second command uses the Set-Service cmdlet to change the status of the Schedule service to “Stopped”. It uses the InputObject parameter to submit the service stored in the $s Variable, and it uses the Status parameter to specify the desired status.

Remove-WSManInstance

NAME
    Remove-WSManInstance

SYNOPSIS
    Deletes a management resource instance.

SYNTAX
    Remove-WSManInstance [-ApplicationName <string>] [-ComputerName <string>] [-Port <int>] [-UseSSL] [[-SelectorSet] <hashtable>] [-AuthenticationMechanism <AuthenticationMechanism>] [-Credential <PSCredential>] [-OptionSet <hashtable>] [-ResourceURI <Uri>] [-SessionOption <hashtable>] [<CommonParameters>]

    Remove-WSManInstance [-ConnectionURI <Uri>] [[-SelectorSet] <hashtable>] [-AuthenticationMechanism <AuthenticationMechanism>] [-Credential <PSCredential>] [-OptionSet <hashtable>] [-ResourceURI <Uri>] [-SessionOption <hashtable>] [<CommonParameters>]

DESCRIPTION
    The Remove-WSManInstance deletes an instance of a management resource that is specified in the ResourceURI and SelectorSet parameters.

    This cmdlet uses the WinRM connection/transport layer to delete the management resource instance.

PARAMETERS
    -ApplicationName <string>
        Specifies the application name in the connection. The default value of the ApplicationName parameter is “WSMAN”. The complete identifier for the remote endpoint is in the following format:

             <transport>://<server>:<port>/<ApplicationName>

        For example:

             http://server01:8080/WSMAN

        Internet Information Services (IIS), which hosts the session, forwards requests with this endpoint to the specified application. This default setting of “WSMAN” is appropriate for most uses. This parameter is designed to be used when numerous computers establish remote connections to one computer that is running Windows PowerShell. In this case, IIS hosts Web Services for Management (WS-Management) for efficiency.

        Required?                    false
        Position?                    named
        Default value                WSMan
        Accept pipeline input?     false
        Accept wildcard characters? false

    -AuthenticationMechanism <AuthenticationMechanism>
        Specifies the authentication mechanism to be used at the server. Possible values are:

        – Basic: Basic is a scheme in which the user name and password are sent in clear text to the server or proxy.
        – Default : Use the authentication method implemented by the WS-Management protocol. This is the default.
        – Digest: Digest is a challenge-response scheme that uses a server-specified data string for the challenge.
        – Kerberos: The client computer and the server mutually authenticate by using Kerberos Certificates.
        – Negotiate: Negotiate is a challenge-response scheme that negotiates with the server or proxy to determine the scheme to use for authentication. For example, this parameter value allows negotiation to determine whether the Kerberos protocol or NTLM is used.
        – CredSSP: Use Credential Security Service Provider (CredSSP) authentication, which allows the user to delegate credentials. This option is designed for commands that run on one remote computer but collect data from or run additional commands on other remote computers.

        Caution: CredSSP delegates the user’s credentials from the local computer to a remote computer. This practice increases the security risk of the remote operation. If the remote computer is compromised, when credentials are passed to it, the credentials can be used to control the network session.

        Required?                    false
        Position?                    named
        Default value
        Accept pipeline input?     false
        Accept wildcard characters? false

    -ComputerName <string>
        Specifies the computer against which you want to run the management operation. The value can be a fully qualified domain name, a NetBIOS name, or an IP address. Use the local computer name, use localhost, or use a dot (.) to specify the local computer. The local computer is the default. When the remote computer is in a different domain from the user, you must use a fully qualified domain name must be used. You can pipe a value for this parameter to the cmdlet.

        Required?                    false
        Position?                    named
        Default value                localhost
        Accept pipeline input?     false
        Accept wildcard characters? false

    -ConnectionURI <Uri>
        Specifies the connection endpoint. The format of this string is:

             <Transport>://<Server>:<Port>/<ApplicationName>

        The following string is a properly formatted value for this parameter:

             http://Server01:8080/WSMAN

        The URI must be fully qualified.

        Required?                    false
        Position?                    named
        Default value
        Accept pipeline input?     false
        Accept wildcard characters? false

    -Credential <PSCredential>
        Specifies a user account that has permission to perform this action. The default is the current user. Type a user name, such as “User01”, “Domain01\User01”, or “User@Domain.com”. Or, enter a PSCredential object, such as one returned by the Get-Credential cmdlet. When you type a user name, you will be prompted for a password.

        Required?                    false
        Position?                    named
        Default value
        Accept pipeline input?     true (ByPropertyName)
        Accept wildcard characters? false

    -OptionSet <hashtable>
        Passes a set of switches to a service to modify or refine the nature of the request. These are similar to switches used in command-line shells because they are service specific. Any number of options can be specified.

        Specifies the port to use when the client connects to the WinRM service. When the transport is HTTP, the default port is 80. When the transport is HTTPS, the default port is 443. When you use HTTPS as the transport, the value of the ComputerName parameter must match the server’s Certificate common name (CN). However, if the SkipCNCheck parameter is specified as part of the SessionOption parameter, then the Certificate common name of the server does not have to match the host name of the server. The SkipCNCheck parameter should be used only for trusted computers.

    -ResourceURI <Uri>
        Contains the Uniform Resource Identifier (URI) of the resource class or instance. The URI is used to identify a specific type of resource, such as disks or processes, on a computer.

        A URI consists of a prefix and a path to a resource. For example:

             http://schemas.microsoft.com/wbem/wsman/1/wmi/root/cimv2/Win32_LogicalDisk
             http://schemas.dmtf.org/wbem/wscim/1/cim-schema/2/CIM_NumericSensor

        Default value
        Accept pipeline input?     false
        Accept wildcard characters? false

    -SelectorSet <hashtable>
        Specifies a set of value pairs that are used to select particular management resource instances. The SelectorSet parameter is used when more than one instance of the resource exists. The value of the SelectorSet parameter must be a hash table.

        The following example shows how to enter a value for this parameter:

            -SelectorSet @{Name=”WinRM”;ID=”yyy”}

        Required?                    false
        Position?                    2
        Default value
        Accept pipeline input?     true (ByValue, ByPropertyName)
        Accept wildcard characters? false

    -SessionOption <hashtable>
        Defines a set of extended options for the WS-Management session. Enter a SessionOption object that you create by using the New-WSManSessionOption cmdlet. For more information about the options that are available, see New-WSManSessionOption.

        Required?                    false
        Position?                    named
        Default value
        Accept pipeline input?     false
        Accept wildcard characters? false

    -UseSSL [<SwitchParameter>]
        Specifies that the Secure Sockets Layer (SSL) protocol should be used to establish a connection to the remote computer. By default, SSL is not used.

        WS-Management encrypts all the Windows PowerShell content that is transmitted over the network. The UseSSL parameter lets you specify the additional protection of HTTPS instead of HTTP. If SSL is not available on the port that is used for the connection and you specify this parameter, the command fails.

Restart-Computer

NAME
    Restart-Computer

SYNOPSIS
    Restarts (“reboots”) the operating system on local and remote computers.

SYNTAX
    Restart-Computer [[-ComputerName] <string[]>] [[-Credential] <PSCredential>] [-AsJob] [-Authentication {Default | None | Connect | Call | Packet | PacketIntegrity | PacketPrivacy | Unchanged}] [-Force] [-Impersonation {Default | Anonymous | Identify | Impersonate | Delegate}] [-ThrottleLimit <int>] [-Confirm] [-WhatIf] [<CommonParameters>]

DESCRIPTION
    The Restart-Computer cmdlet restarts the operating system on the local and remote computers.

    You can use the parameters of Restart-Computer to run the restart operations as a background job, to specify the authentication levels and alternate credentials, to limit the operations that run concurrently, and to force an immediate restart.

    This cmdlet does not require Windows PowerShell remoting unless you use the AsJob parameter.

PARAMETERS
    -AsJob [<SwitchParameter>]
        Runs the command as a background job.

        Note: To use this parameter, the local and remote computers must be configured for remoting and, on Windows Vista and later versions of Windows, you must open Windows PowerShell with the “Run as administrator” option. For more information, see about_remote_requirements.

        When you use the AsJob parameter, the command immediately returns an object that represents the background job. You can continue to work in the session while the job completes. The job is created on the local computer and the results from remote computers are automatically returned to the local computer. To manage the job, use the Job cmdlets. To get the job results, use the Receive-Job cmdlet.

        For more information about Windows PowerShell background jobs, see about_jobs and about_remote_Jobs.

        Required?                    false
        Position?                    named
        Default value
        Accept pipeline input?     false
        Accept wildcard characters? false

    -Authentication <AuthenticationLevel>

    <CommonParameters>
        This cmdlet supports the common parameters: Verbose, Debug,
        ErrorAction, ErrorVariable, WarningAction, WarningVariable,
        OutBuffer and OutVariable. For more information, type,
        “Get-Help about_CommonParameters“.

INPUTS
    None
        You cannot pipe input to this cmdlet.

OUTPUTS
    None or System.Management.Automation.RemotingJob
        When you use the AsJob parameter, the cmdlet returns a job object. Otherwise, it does not generate any output.

NOTES

        This cmdlet uses the Win32Shutdown method of the WMI WIN32_OperatingSystem class.

    ————————– EXAMPLE 1 ————————–

    C:\PS>Restart-Computer

    Description
    ———–
    This command restarts the local computer.

    ————————– EXAMPLE 2 ————————–

    C:\PS>Restart-Computer -ComputerName Server01, Server02, localhost

    Description
    ———–
    This command restarts two remote computers, Server01 and Server02, and the local computer, identified as “localhost”.

    ————————– EXAMPLE 3 ————————–

    C:\PS>$j = Restart-Computer -ComputerName Server01, Server02 -AsJob

    C:\PS> $results = $j | Receive-Job

    C:\PS> $results

    Description
    ———–
    These commands run a Restart-Computer command as a background job on two remote computers, and then get the results.

    The first command uses the AsJob parameter to run the command as a background job. The command saves the resulting job object in the $j Variable.

    The second command uses a pipeline operator to send the job object in $j to the Receive-Job cmdlet, which gets the job results. The command saves the results in the $results Variable.

    The third command displays the result saved in the $results Variable.

    Because the AsJob parameter creates the job on the local computer and automatically returns the results to the local computer, you can run the Receive-Job command as a local command.

    ————————– EXAMPLE 4 ————————–

    C:\PS>Restart-Computer -comp Server01 -Impersonation anonymous -Authentication PacketIntegrity

    Description
    ———–
    This command restarts the Server01 remote computer. The command uses customized impersonation and authentication settings.

    ————————– EXAMPLE 5 ————————–

    C:\PS>$s = Get-Content domain01.txt

    C:\PS> $c = Get-Credential domain01\admin01

    C:\PS> Restart-Computer -ComputerName $s -Force -ThrottleLimit 10 -Credential $c

    Description
    ———–
    These commands force an immediate restart of all of the computers in Domain01.

    The first command gets a list of computers in the domain and saves it in the $s Variable.

    The second command gets the credentials of a domain administrator and saves them in the $c Variable.

    The third command restarts the computers. It uses the ComputerName parameter to submit the list of computers in the $s Variable, the Force parameter to force an immediate restart, and the Credential parameter to submit the credentials saved in the $c Variable. It also uses the ThrottleLimit parameter to limit the command to 10 concurrent connections.
