I am trying to make a new domain controller on a new network. The system was a fresh install of Windows Server 2008 R2 with SP1 installed. When I try to promote it using dcpromo it tells me the domain is already in use on the network. There isn't even another machine connected to the network it is on so I am not sure what to do.
Any suggestions on what might be stored in the registry somewhere making it think the domain is in use?
