 This blog is good in case you need to unjoin a PC or a Server from your domain. Maybe the employee no longer works there, you are decommissioning an old laptop that is being disposed or a server is EOL and being replaced. You can unjoin a Windows Server 2019 Server from a domain in the GUI and PowerShell

GUI

Click Start then go to Server Manager
Click Local Server then click domain name
Click Change
Click the Workgroup radio button and type any value then click OK
Click OK
Click OK
Click OK
Click Close
Click Restart Now

PowerShell

Click Start then click Windows PowerShell
Type


    

  • remove-computer -credential domain\domainadminid -passthru -verbose; restart-computer
    • 


For Example


    

  • remove-computer -credential company\administrator -passthru -verbose; restart-computer
    • 


Type credentials with permission to leave the domain and click OK







Type Y and hit enter to continue. The server reboots and is no longer joined to the domain





Join us in our next blog where we will be installing another Windows server but this time choosing the Server Core option!
