Question : Server Replication.

To All,

On my DHCP/DNS Server which I recently have been taskes to manage, I have been noticing these two errors being logged in the directory service viewer.

"This server is the owner of the following FSMO role, but does not consider it valid. For the partition which contains the FSMO, this server has not replicated successfully with any of its partners since this server has been restarted. Replication errors are preventing validation of this role. "

And Then the second error is

"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.. "

On my BDC Windows is loggin the following errors

"The File Replication Service is having trouble enabling replication from Srver Name to Server Name for c:\windows\sysvol\domain using the DNS name cmxappfpserver.CMXINTRANET.local. FRS will keep retrying. "

So it would be safe to say that these I ran the repadmin /showrepl and suprisingly to my shock these servers haven't succesfully replicated in over 2 years. I would appreciate any assistance given,

Answer : Server Replication.

If these are the only two domain controllers and they exist on the same network subnet here is what I would suggest that you do:

Make the PDC FSMO role holder the base DNS we will call it.  Point your other DC to this one as primary DNS.  Do an ipconfig /registerdns on the box that you point at the PDC FSMO holder.  Look on this PDC system for the server to have correctly registered.  If it has then from the PDC FSMO holder run dcdiag and netdiag as I stated at the start of this ticket.  See if the result has improved.
