Hi,

I recently noticed my sites were not replicating and I received the following error:

It has been too long since this machine last replicated with the named source machine. The time between replications with this source has exceeded the tombstone lifetime. Replication has been stopped with this source.
The reason that replication is not allowed to continue is that the two machine's views of deleted objects may now be different. The source machine may still have copies of objects that have been deleted (and garbage collected) on this machine. If they were allowed to replicate, the source machine might return objects which have already been deleted.
Time of last successful replication:
<date> <time>
Invocation ID of source:
<ID>
Name of source:
<source name>
Tombstone lifetime (days):
<number>

The replication operation has failed.

User Action:
Determine which of the two machines was disconnected from the forest and is now out of date. You have three options:

1. Demote or reinstall the machine(s) that were disconnected.
2. Use the "repadmin /removelingeringobjects" tool to remove inconsistent deleted objects and then resume replication.
3. Resume replication. Inconsistent deleted objects may be introduced. You can continue replication by using the following registry key. Once the systems replicate once, it is recommended that you remove the key to reinstate the protection.
Registry Key:
HKLM\System\CurrentControlSet\Services\NTDS\Parame ters\Allow Replication With Divergent and Corrupt Partner

My DC's are replicating but the KCC and automatic connections have elected to have them traverse through my slowest connection in Singapore. When I added a manual AD connection from Chicago -> London, etc I would get the error above. I added the registry key per option 3 to both DC's after testing the global replication was working to ensure I did not have lingering deleted objects, etc. I also rebooted the two subject DC's and they are still not working? I only have one DC in each location so I can't run dcpromo to demote and re-promote.

Thanks

Roger
