We currently have 3 domain controllers (2 running W2008, 1 running W2000 - soon to be retired) within a single domain.
All DC's are Virtual Machines (running under VMWare). At the weekend our primary domain controller (the one with the FSMO, PID etc. - running Windows 2008) crashed during its vRanger Back-Up putting the server into a down/off state for about 14 hours.
After trying to boot the server a VMware error message kept appearing - I mananged to sort out this error which was caused by a corrupt snapshot
At present, the domain is still functioning - people can still login, I can add new machines, passwords can be changed, DNS, DHCP and WINS still OK
When the Domain Controller came back on-line everything seemed OK but after looking in the event log - Directory Services it shows 3 warning mesages (Event Id 2093) and 3 error messages (Event Id 1863)
On the failed server when I try to access the Active Directory Users and Computers module it displays the following error - 'Naming information cannot be located because: The target principle name is incorrect'
I think that the primary controller is out-of-sync with the other two controllers - how do I go about getting everything back in-sync again
