I have two Domin Controllers and one of the domain controller is running DNS and the other was succesfully replicating until this week. I am now getting Event ID 2087 NTDS Replication - DS RPC Client. I click on the backup DNS now and it says its not configured. I want this domain controller to also run DNS (as it was) in the case that the first Domain controller fails then the back domain controller will enable DNS management.
Any detailed help on how to diagnose and resolve will be GREATLY appreciated
