How to move your mail infrastructure away from Lotus Notes

So your DC is Tombstoned

For the tombstoned DC server do this:

Open a command prompt on any DC and enter the following from a command prompt:

repadmin /replicate DC=corp5,DC=cmtsandbox,DC=com

You should get this:

DsReplicaSync() failed with status 8614 (0x21a6):

The directory service cannot replicate with this server because the time since the last replication with this server has exceeded the tombstone lifetime.

Magic time:

1. Sign on to server2
2. Start the registry editor (regedit)
3. Navigate to HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\NTDS\Parameters
4. Add the following dword (32) key (Allow Replication With Divergent and Corrupt Partner)
5. Press enter. Go back in and set the value to 1.

Best Practice - Enter the following:

Repadmin /removelingeringobjects server1 c67ea6e9-0b28-44aa-8620-71e9b5dc3c55 DC=corp5,DC=cmtsandbox,DC=com /advisory_mode

Repadmin /removelingeringobjects server2 0345ba41-8ab2-4f31-be2e-6a9f45d75e49 DC=corp5,DC=cmtsandbox,DC=com /advisory_mode

***(Repadmin /removelingeringobjects ServerWithLingeringObjects CleanServerGUID NamespaceContainingLingeringObject /advisory_mode)- Original command

This is how you get the GUID

repadmin /showrepl server1

DSA Options: IS_GC
Site Options: (none)
DSA object GUID: c67ea6e9-0b28-44aa-8620-71e9b5dc3c55
DSA invocationID: c67ea6e9-0b28-44aa-8620-71e9b5dc3c55

repadmin /showrepl server2

DSA Options: IS_GC
Site Options: (none)
DSA object GUID: 0345ba41-8ab2-4f31-be2e-6a9f45d75e49
DSA invocationID: 8e8249b4-faa8-45f7-87a3-46b2352939f2

If there is an error, assess, then rerun without /advisory_mode

Reboot if an error was found. If not continue:

repadmin /replicate DC=corp5,DC=cmtsandbox,DC=com

repadmin /replicate DC=corp5,DC=cmtsandbox,DC=com

You should now get:

Sync from to completed successfully.

Whoo hoo – Done.
