This morning, my system is showing the following alert.
Could not determine the FSMO role holder.
AD Replication Partner Op Master Consistency : Unable to determine domain naming Op Master on domain controller ‘<myDC>’.
At the same time, I see another alert.
AD Client Side – Script Based Test Failed to Complete
AD Replication Partner Op Master Consistency : The script ‘AD Replication Partner Op Master Consistency’ failed to executethe following LDAP query: ‘<LDAP://dc3.chemistry.ohio-state.edu/CN=Configuration,DC=chemistry,DC=ohio-state,DC=edu>;(&(objectClass=crossRefContainer)(fSMORoleOwner=*));fSMORoleOwner;Subtree’. The error returned was ‘The server is not operational.’ (0x80040E37)
This is happening because my DC’s are backing up with VMWare VDR in the middle of the night, and the rule is set to run every 60 seconds. Per the referenced blog post below, I set the rule to 12 mins (seems like enough). I still might get the error though — I really need to sit down and figure out how to set PC’s in maintenance mode when quiesced snapshots are taken. It should be trivially easy, according to the VMWare tech manuals.
