If you have installed Windows Home Server 2011, you will notice the workgroup name is WORKGROUP and you can’t change it. Well, Diehard was good enough to post in our forums how to do it and I have expanded on it here.
[box type=”alert” style=”rounded” border=”full”]WARNING: Some people are reporting that once they have changed the WORKGROUP name that the Dashboard will no longer load. The only way to fix this is to perform a server reinstall, so if you not sure DO NOT attempt to change the WORKGROUP name.[/box]
So here are the steps you need to follow to change the Workgroup name to match your network:
Use Remote Desktop Connection and connect to the server (of if you have a monitor, keyboard and mouse connected to the server just go to the desktop)
Start > Right-click Computer > Manage
Under Roles Summary section, click Remove Roles on the right side
Uncheck Active Directory Certificate Services and click Next
