Having a frustrating problem with one Windows 2000 DC and two Windows 2003 DC's.
If the Windows 2000 DC is down and I reboot my Windows 2003 DC's both DC's hang at "preparing network connections". After I boot the Windows 2000 DC up, both Windows 2003 DC's start. The FSMO roles have already been moved to one of the Windows 2003 boxes.
I've run dcdiag and netdiag and both have passed my server. I've found that if I shutdown the 2003 DC's and stop the DNS service on the Windows 2000 box that they hang at "preparing network connectons". I get LSASRV 40960 errors in my event log.
Have tried disabling KDC used netdom to reset machine password and then restarted the KDC (and rebooted server). Also given network services full access to the following registry keys.
I have multiple network cards on the servers. On the 2003 servers I have disabled the addition NIC's and confirmed that the machine is pointing to its own DNS via nslookup.
Completely stuck as I want to remove the Windows 2000 DC from the domain.
