I'm having an issue installing an additional domain controller on a Windows Server 2008 domain (server is 32bit). The new server is a server 2008 R2 (64bit)
I have tried to run the adprep /forestprep and adprep /domainprep on the current domain controller with the Server 2008 (32Bit) media but the message is coming up that the information has already been updated.
When I go to dcpromo the new server 2008 R2 it comes up with message saying that I need to run the adprep.
The new server is part of the domain and this shouldn't be a replication issue as nothing has been run.
