I just setup 2 DC (DC1 and DC2) in my single domain environment. Both of them running 2003. and they point to themselves for DNS. Also they are AD-Intergrated.
There were no problem at all during dcpromo. Everything looks fine. But after I set DC2 as GC, I run the replication, it returns me the error mesage as shown in screenshot. But it's fine when I replicate from DC1( first DC in my domain). I really have no idea what is wrong.
