one event is being logged on one DC because the source DC contains a lingering object which does not exist on the local DCs copy of Active Directory Domain Services database and the local DC does *not* have the following registry key enabled to ensure strict replication consistency. Strict replication consistency prevents lingering objects residing on a source DC from re-replicating to a destination DC that has already processed the deletion.  Since this registry key is not set, the object will be re-replicated and recreated in the local Active Directory Domain Services database. 
 how to t identify and remove all lingering objects in the forest, starting with the writable and read-only partitions containing the object referenced in this event, and then enable the following registry key to ensure strict replication consistency.

"The solutions and answers provided on Experts Exchange have been extremely helpful to me over the last few years. I wear a lot of hats - Developer, Database Administrator, Help Desk, etc., so I know a lot of things but not a lot about one thing. Experts Exchange gives me answers from people who do know a lot about one thing, in a easy to use platform." -Todd S.

Your first step is to perform a Metadata cleanup. This will cleanup most of the objects that might be lingering from other past DC's that were not properly removed.

Metadata Cleanup

Another thing is to remove SRV records that exist in the folder in the DNS console.

Also in AD Sites and Serivces Delete any DC computer objects that are present that do NOT have NTDS settings.

That is fine. You still need to perform the metadata cleanup.
