I Have a single domain with a single DC (Server 2003) that has been giving me problems. Recently I turned up a new DC, also Server 2003, and moved FSMO, and all related network services. I go to demote the old server and I get a message saying "No other DC's for that domain can be contacted." and continues to warn that if I continue I could lose entire contents of AD. So I thought I'd stop right there and hit the forum. Any thoughts?
