Can't logon as Domain Administrator after DCPROMO

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.

Any ideas?

Any error message when you tried to logon as a domain administrator.

When you login as a domain user, can you run dsa.msc and find domain admin and which are the users under it?

Now that is strange, it works after two hours. The only modification I made was to AD when I investigated the Administrator account, I noticed that under the account tab, the User logon name and domain was blank, but it contained information for pre-Windows 2000. Anyhoo, that appears to have fixed it. I appreciate the prompt response.
