We just bought a Windows 2008 R2 server for specific purposes that would never require user interaction. But now we may need to fold it into our domain, if possible.
The issue is that the domain is being driven by an SBS 2011 server.
Can we migrate AD to this Windows 2008 R2 server, bringing all usernames and passwords, and keep it sync'ed with the SBS 2011 server? I.e., can we run SBS 2011 as a PDC and the Windows 2008 R2 box as a BDC?
The PDC is stored in one location, and the BDC is stored in another location. We have a Cisco S2S tunnel connecting the two.
