    If your computer was a member of a domain before you joined the workgroup, it will be removed from the domain and your computer account on that domain will be disabled.


  • If your network includes computers running Windows XP, you might need to change the workgroup name on those computers to match the workgroup name on the computers running this version of Windows so that you can see and connect to all computers on your network.
