I have a network w/ 2 Win2K3 servers running Active Directory. I am adding a Win2k8 R2 server to the domain. I have successfully run adprep /forestprep, /domainprep and /gpprep on the primary 2K3 server. However, when I attempt to join the 2K8 machine I still get this error:
To install a domain controller into this Active Directory forest, you must first prepare the forest using 'adprep /forestprep'.
Any ideas where to go from here?
