Hi,

I getting the following error on one of my DC's and it is preventing it from being replicated to:

Event ID: 1925

The attempt to establish a replication link for the following writable directory partition failed.
 
Directory partition:
CN=Schema,CN=Configuration,DC=ThreeRivers,DC=local
Source directory service:
CN=NTDS Settings\0ACNF:c5b4e052-8d72-4c19-8ebf-fe1cb86b1242,CN=TR-VM-EDC-DC01,CN=Servers,CN=Default-First-Site-Name,CN=Sites,CN=Configuration,DC=ThreeRivers,DC=local
Source directory service address:
c5b4e052-8d72-4c19-8ebf-fe1cb86b1242._msdcs.ThreeRivers.local
Intersite transport (if any):
 
 
This directory service will be unable to replicate with the source directory service until this problem is corrected.
 
User Action
Verify if the source directory service is accessible or network connectivity is available.
 
Additional Data
Error value:
8259 A referral loop was detected by the client.

When I look in Sites and Services I see that for reason or another I see the its own server name listed under the NTDS Settings.  When I go and delete it then it automatically recreates itself.

I am able to force replicate this server to the main dc but the main dc is unable to replicate with this server stating that the server is in the process of being removed.

On the server with the issue I also something that I have never seen before and that is that it has 2 NTDS settings for some reason.  If I try to delete it then it wants to remove the entire server from Sites And Services

I think you need to forcefully demote that 2012 ADC
http://terrytlslau.tls1.cc/2012/03/domain-controller-demotion-on-windows.html

Clear its all metadata from active directory
http://technet.microsoft.com/en-us/library/cc816907(v=ws.10).aspx

The re join its to domain again as member server
Download Portqueryui from Microsoft and check all ports are open as appropriate

If all ports are opened, you can promote it to ADC

Thank you.  Demoting the DC and re-promoting it was the only solution
