I have a domain with an NT 4.0 server as PDC. I could not upgrade the NT 4.0
to W2K because of a driver issue, so I set up another PC as a NT 4.0 BDC, I
upgraded it to PDC, and then I installed W2K Server on it with SP4. I had a
problem with disjointed DNS, but now the new W2K DC is server08.ourdomain.org
and the Domain is ourdomain.org in the Network Identification tab under
System Properties. Another existing W2K server on the network has Full
Computer Name: server04.ourdomain.org and Domain: ourdomain (there is no
..org). When I run DCPROMO on this server, I get the 5171 error. The HKEY
Tcpip Parameters are the same for the two PC's, i.e. Domain and NV Domain is
ourdomain.org and the Hostname and NV Hostname are server08 and server04
respectively. I don't know how to fix this.
