DCPROMO failed

By rsears ·
I upgraded the first NT4 domain controller in my domain without any issues, its running AD and DNS seems to be working fine. I have other NT BDCs and W2K stand alone servers I would like to upgrade to W2K DCs. I ran DCPROMO on a standalone server, while running the active directory wizard I got an error that said.

The operation failed because:

Failed finding a suitable domain controller for the domain mydomain.com


The specified domain either does not exist or could not be contacted.

The W2K domain DC seems to be working fine and there isn?t any indication there are any problems. The standalone is a member of the domain and is showing up in the DNS forward and reverse zones on the DC. DNS is set for dynamic updates. I havetried to run DCPROMO with, and without DNS running on the prospective DC candidate and have failed. Got any ideas? It seemed like it would be straightforward upgrade, only one domain, nothing fancy.

Hi,
Since this stand alone server was made a member of NT4 domain when it was installed, it would have used old naming schemes.
From that standalone server, remove the domain membership and recreate the membership with your already upgraded win2k DC. I am not sure on this, but you can give a try,

regards

I tried this but it did not work, then I modified the TCP/IP properties of the first DC machine to use itself as the first DNS server, then I set the DNS properties on the prospective DC candidate the same way and ran DCPROMO, and it worked. Thanks for the suggestion though.
