Our network topography includes a Primary Domain Controller (Win 2K) and a
vestigial BDC (Windows NT) which operates in a branch office. Our subnetted
network operates over a dedicated VPN service, which is 99.9% reliable.
Recently we encountered a prolonged down time due to some network changes we
initiated, and one of the branch office IT guys promoted the NT BDC to a PDC
(or it promoted itself!)
When we restored the interoffice VPN, we discovered that the field office DC
(now a PDC) showed the original PDC (Win2K) located in our main office as a
BDC. And, the original PDC (main office) showed the branch office PDC as a
BDC (correct to the orignal PDC, but not, actually, how the branch office
machine was currently configured).
In either case, we brought the VPN link back up and, to our dismay, we can't
find a way to get the NT (branch office) PDC demoted back to BDC. We tried
using the SRVMGR tool in the NT RK to promote the original PDC (listed as a
BDC on the NT branch office machine) back to PDC, but that action fails with
an "error 0050. Network request is not supported."
We've tried to remove and restore the NT machine, but to no avail. The
secure channels appear to be working, but we have TWO PDCs in the domain from
the NT machine's POV, and it's causing NETLOGON problems.
How do we fix this?
