I have two DCs on my network. One is a Windows 2000 and one is 2003 R2. The R2 is a running as a virtual machine. The 2000 is a physical pc. The 2003 DC was just created in the last day to replace a failing 2003 64 bit machine. I migrated all the FSMO and GC to the new machine, and then demoded the 64 bit server. I then rebuilt the 64 bit machine and placed the 2003 R2 DC on it running under virtual server. I now want to demode the 2000 Server and replace its OS with 2003 R2 and convert the AD mode to 2003. The issues I have is if I turn off the Server 2000 some local users cannot do things that require domain services , also any thing that seems to require a login on the 64 bit Sever takes forever (about 10 minuest to login to windows). I checked the DNS and that is not the issue as best I can tell as all DC network names resolve instantly. How do I figure out what is happening?
