I’m getting following error in eventlog: The Active Directory Domain Services Installation Wizard (Dcpromo) was unable to establish connection with the following domain controller. Domain Controller: servername.domain.local Additional data: Error value: 1908 Could not find the domain controller for this domain. I have also run dcdiag on 2003 server and it shows no errors.
