I recently promoted a Win2k8 Server to a DC while part of a Win2k3 environment. It promoted as it should have. Active Directoy Users and Computers etc. was all there. I then removed the Win2k3 DC from the domain and now I can't join anything to the domain because it can't find a DC. I've checked DNS and it looks good. Can't create a new user because RPC server is unavailable. Anyone know where to start? Nobody can get to shares, printers etc.
