I'm trying to add a new Windows Server 2008 Standard DC to my current W2K3 AD domain. When running dcpromo on the W2K8 box it tells me to run adprep /forestprep & adprep /domainprep on the existing W2K3 DC using the adprep.exe from the W2K8 install media in order to prepare the domain. I have tried this but running adprep simply does.. nothing..
Going back to the W2K8 box, same error message. The logged on user account is member of the Schema Admins group. Any ideas?
