Re: Unknown Objects prevent replication

A schema mismatch means the schema's are out of whack and the DCs aren't even getting close to replicating objects outside of the schema.

Two objects really can't have the same DN. There is something different about them. How about you use adfind or dsquery or some other command line tool to dump the container DNs and post them.

We have a customer we've been called upon to solve a tricky situation: Single Domain forest with one DC only. When trying to add a second DC, replication of the Domain NC failed (Schema and Config NC are okay) because of error Schema mismatch. It appears to be two objects in the container CN=Operations,CN=DomainUpdates,CN=System,DC=Domain,DC=com that are of unknown Class on the source DC are causing this. These 2 oibjects are part of an adprep install he tried (and according to adprep logs was okay). Still, these two objects are the problem. Since he never upgraded any of his DC's to W2K3 and wil be retiring his domain in 9 months, I was wondering if it is okay to delete these two objects
Both objects have the same DN (CN=6bcd568d-8314-11d6-977b-00c04f613221,CN=Operations,CN=DomainUpdates,CN=System,DC=domain,DC=com). My first reaction is to remove these two objects. I have a feeling they don't need them at all. To be on the safe side, I would like to hear from one of you, experts, if you share my opinion.
