[Samba] Resolving Schema & Configuration Replication Issues

[Adam Tauno Williams]

I have three S4 DCs (Sernet 4.5.2) all in happy replication, and a  
Windows 2008r2 DC to which the Exchange scema was added - it has  
failed to replication the schema/configuration ever since [yet  
consultants forged onwards].

It is possible to attempt to retry the replication somehow - we have  
since update the S4 DCs.  Something like a "drs replicate --full-sync"?

Would it be better to back out the 2008r2DC and re-do the process?  
[which will not make people happy, but...].
