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.

Join a workgroup named WORKGROUP.
PS C:>Add-Computer -WorkGroupName WORKGROUP
Unjoin server from the current domain using the contosoadministrator account.
PS C:>Remove-Computer -UnjoinDomaincredential CONTOSOAdministrator -Passthru -Verbose -Restart
