I'm trying to install a new SBS2011 server in an existing SBS2003 domain. The SBS2003 server is the only domain controller in the domain. All the prerequisites for the 2011 upgrade have been completed. When I run the SBS 2011 Standard Migration Preparation Tool on the SBS2003 server, I get an error at the 'Scan the source server for problems' screen:
Found an offline domain controller present in Active Directory: Server: Server.mydomain.local
The server that is referenced is the SBS2003 server! I checked all the FSMO roles, they all point to the SBS2003 server. I also confirmed that the SBS2003 server is the only domain controller in the environment and it's the only server in the Domain Controllers OU. I also ran DCDIAG /V and confirmed that there aren't any problems.
I found a few other posts with the same problem, but no fixes.
