I have a Windows SBS 2003 machine running as the PDC. We are looking to eventually retire this machine, but for the time being, purchased a new server to join to the domain running Windows 2003 R2 Standard and have replication between the two systems. I successfully ran dcpromo on the new machine and rebooted. The new machine came up and I can see that DNS, AD, etc.. have replicated between the two machines; however, I am unable to login to the new Domain Controller as the domain administrator. I can login as another user in AD, but not the Admin account.
