be just this one branch server. Other branch domain controllers that replicate with CENTRALDC-02 are fine. On SINGAPOREDC, the RpcSs.exe is listening on TCP port 135. It is open in the firewall, and querying the port https://support.microsoft.com/en-us/kb/2102154 returns that it is listening. It's also listening on ports 389, 3268, and 3269. Performing a dcdiag /test:replications on SINGAPOREDC shows errors 1256 (The remote system is not available) and 1722 (The RPC server is unavailable) replicating from the central DC to the branch DC. No errors running this on the central DC. Performing repadmin /replsummary also shows error 1722, with 4 fails out of 5 attempts. I have rebooted both of these https://community.spiceworks.com/topic/653215-replication-problem-rpc-server-unavailable-error-1722 DCs. The RPC service is running. It appears to have all of its DNS records in place. Forcing a replication via Sites & Services sometimes throws an error saying it can't communicate with the server. Performing dcdiag /test:dns /v /e on SINGAPOREDC gives many errors, as shown below. Note that while it fails communicating with some domain controllers, it passes for others. Got this error for several but not all domain controllers.

DOMAIN-DC1 rpc server is and DOMAIN-DC2 are both Windows 2012 R2 Standard Domain Controllers. I have no antivirus software installed that could be causing the problem. Any help greatly appreciated!

errors then repadmin /replsum works fine. I have forest level 2008 R2 with Windows Server 2008 R2, Windows 2012 core and Windows 2012 R2 servers running as DCs in five different locations and different subnets. March 16th, 2015 9:44pm I would recommend that you start with that especially the IP setting recommendations: http://www.ahmedmalek.com/web/fr/articles.asp?artid=23 I also recommend that you dcdiag to check that your DCs are in healthy state.

RPC error 1722 / 0x6ba / RPC_S_SERVER_UNAVAILABLE is logged when a lower layer protocol reports a connectivity failure. The common case is that the abstract TCP CONNECT operation failed. In the context of AD replication, the RPC client on the destination DC was not able to successfully connect to the RPC server on the source DC.
