I have an existing Dell Poweredge server running Windows 2000 Server SP4. I have another Dell Poweredge server now running Windows 2003 Server R2 Standard joined to the domain of the Windows 2000 Server. Everything rocks along fine. I can see the existing server, communicates fine. DNS is setup perfectly and replicated from the 2000 server perfectly.
I would like to now install Active Directory on the 2003 server and add it to the existing 2000 AD domain. However, I continue to receive the "the version of the source active directory is incompatible with the version on this computer" message. I have run ADPREP /FORESTPREP, /DOMAINPREP and /DOMAINPREP GPPREP and everything completed successfully but I'm still receiving the error. No errors in the event viewer. It just simply will not work.
Anybody have any ideas?
