Running Windows Core: How-to view domain and join/unjoin domain

Running Windows Core Series, getting on and off the domain.

When running these commands or using them in scripts keep in mind that some may become deprecated in future versions of Windows. Best practice is to use the PowerShell commands when possible to future proof any script that use these commands. These commands were run on Windows Server 2012R2.

When running Windows Server 2012+ without a GUI note that the GUI can be reinstalled via PowerShell (Install-WindowsFeature) and a reboot.

From Windows Server core command prompt:

Display current domain information using AD management tools.

C:>POWERSHELL

PS C:>Get-ADDomain

Display domain from command prompt.

C:>WMIC COMPUTERSYSTEM LIST BRIEF

Display current logged on user’s domain.

C:>ECHO %USERDOMAIN%

Join a domain named CONTOSO.

C:>POWERSHELL

PS C:>Add-Computer -DomainName CONTOSO -Restart

Join a workgroup named WORKGROUP.

C:>POWERSHELL

PS C:>Add-Computer -WorkGroupName WORKGROUP

Unjoin server from the current domain using the contosoadministrator account.

C:>POWERSHELL

PS C:>Remove-Computer -UnjoinDomaincredential CONTOSOAdministrator -Passthru -Verbose -Restart
