AD replication failing on one domain controller after adding a new 2012 DC

We have a 2008 AD domain.  Presently we have 5 2008 domain controllers with the domain and forest functional levels set at 2008.  Two weeks ago we added a new 2012 DC to the domain.  Four of the five 2008 dc's are functioning properly as is the 2112 domain controller.  We discovered today that one of the 2008 domain controllers has not successfully replicated since shortly after the new 2112 domain controller was added.  We are trying to find the best way to fix the replication problem.  I have attached the dcdiag for the affected domain controller.

How is replication configured?
Did the 2012 server replace an existing DC?
How familiar with REPADMIN  are you?
Are you receiving event log errors on this or other DCs?
What, if any, roles are held by this server?
One can only presume adprep was run prior to or during the adding of the 2012 server to AD.  Were any issues in the log on the 2012 box noticed at this time?

Replication was configured automatically.  The server in question was getting its replication from two DC's in another site.  I have actually fixed the problem somehow.  I did run repadmin to verify which server was the problem.  I found several fixes online that didn't seem to work, but after trying to recreate the links I rebooted the server again and everything started to work.  Adprep was run prior to installing the new server.  We have four more to create. we are replacing all of our 2008 domain controllers with 2012 so that we can start using dhcp failover.  DHCP has been our biggest problem with outages over the last few years and we are hoping this will fix it.  Any suggestions on pre  or post tasks that we should to when adding these other dc's to avoid this happening again?
