I have nine servers that I am upgrading to Win2k from an exsisting NT 4.0 domain. The domain name is district41.org. The exsisting BDC's upgraded with no problem as member servers. The first PDC upgraded and installed Active Directory with no problem. The second DC upgrade ran into an error when installing Active Directory. The error is that the domain does not exsist in the Forest or Trees. Any ideas?? I'm not sure what my next step should be besides going back to NT 4.0 which is not the best solution.
