xComputerManagement

The xComputerManagement module is a part of the Windows PowerShell Desired State Configuration (DSC) Resource Kit, which is a collection of DSC Resources produced by the PowerShell Team. This module contains the xComputer resource. This DSC Resource allows you to rename a computer and add it to a domain or workgroup.

All of the resources in the DSC Resource Kit are provided AS IS, and are not supported through any Microsoft standard support program or service. The ""x" in xComputerManagement stands for experimental, which means that these resources will be fix forward and monitored by the module owner(s).

Please leave comments, feature requests, and bug reports in the Q & A tab for this module.

If you would like to modify xComputerManagement module, feel free. When modifying, please update the module name, resource friendly name, and MOF class name (instructions below). As specified in the license, you may copy or modify this resource as long as they are used on the Windows Platform.

PowerShell Blog (this is a good starting point). There are also great community resources, such as PowerShell.org, or PowerShell Magazine. For more information on the DSC Resource Kit, check out this blog post.

Examples

Change the Name and the Workgroup Name

This configuration will set a machine name and changes the workgroup it is in.

configuration Sample_xComputer_ChangeNameAndWorkGroup 
{ 
    param 
    ( 
        [string[]]$NodeName ='localhost', 
 
        [Parameter(Mandatory)] 
        [string]$MachineName, 
         
        [Parameter(Mandatory)] 
        [string]$WorkGroupName 
    ) 
      
    #Import the required DSC Resources  
    Import-DscResource -Module xComputerManagement 
 
    Node $NodeName 
    { 
        xComputer NewNameAndWorkgroup 
        { 
            Name          = $MachineName 
            WorkGroupName = $WorkGroupName 
        } 
    } 
}  

Switch from a Workgroup to a Domain

This configuration sets the machine name and joins a domain. Note: this requires a credential.

configuration Sample_xComputer_WorkgroupToDomain 
{ 
    param 
    ( 
        [string[]]$NodeName="localhost", 
 
        [Parameter(Mandatory)] 
        [string]$MachineName, 
 
        [Parameter(Mandatory)] 
        [string]$Domain, 
 
        [Parameter(Mandatory)] 
        [pscredential]$Credential 
    ) 
 
    #Import the required DSC Resources 
    Import-DscResource -Module xComputerManagement 
 
    Node $NodeName 
    { 
        xComputer JoinDomain 
        { 
            Name          = $MachineName  
            DomainName    = $Domain 
            Credential    = $Credential  # Credential to join to domain 
        } 
    } 
}
