I P2Ved a Windows 2003 SP2 clustered node. The conversion process was successfull. After the process was completed, when I try to login to the 2003 server using my domain administrator account the following message appear:
Windows cannot connect to the domain, either because the domain controller is down or unavialable, or because your computer account was not found.
All the services that were stopped in preparation for the conversion was restarted. I can login into the domain controller using local administrator credentials. The computer account was reset sucessfully.
