Join Now One of my branch domain controllers, error 1722 the rpc server is unavailable windows 7 audio SINGAPOREDC is not replicating with its replication partner in our data center, CENTRALDC-02. I discovered the issue when I
Error 1722 The Rpc Server Is Unavailable Windows 10
noticed an updated file in the netlogon folder was not updating everywhere. It seems to be just this one branch server. Other branch domain controllers that replicate with CENTRALDC-02 are https://technet.microsoft.com/en-us/library/replication-error-1722-the-rpc-server-is-unavailable(v=ws.10).aspx fine. On SINGAPOREDC, the RpcSs.exe is listening on TCP port 135. It is open in the firewall, and querying the port 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 https://community.spiceworks.com/topic/653215-replication-problem-rpc-server-unavailable-error-1722 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 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.

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 http://www.winvistatips.com/threads/domain-controllers-synch-in-one-direction-but-not-the-other.687027/ 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 rpc server is the destination DC was not able to successfully connect to the RPC server on the source DC.

is the error message that I get from the one server that is not synchronizing: C:\Documents and Settings\Administrator>repadmin /syncall CALLBACK MESSAGE: Error contacting server fc3ae3ad-d4d2-4e81-a9e9-a2ddc6ba51d7._ msdcs.HCE.local (network error): 1722 (0x6ba): The RPC server is unavailable. CALLBACK MESSAGE: SyncAll Finished. SyncAll reported the following errors: Error contacting server fc3ae3ad-d4d2-4e81-a9e9-a2ddc6ba51d7._msdcs.HCE.local (n etwork error): 1722 (0x6ba): The RPC server is unavailable. I have tried several things including changing the time out settings in the registry but it did not fix it yet. I can synch from the one domain controller to the other but not the other way around. I have checked the DNS and all the settings are the same for both servers (IP is in different subnet but all else works correctly and is as it should be) Any help would be greatly appreciated. Thank you Tom tommy, Oct 27, 2005 #1 Advertisements Paul Williams [MVP] Guest Sounds like the island DNS problem. Configure the DC that isn't replicating to use the DNS server in the other site and restart NETLOGON and the DNS Client service. Then manually trigger replication. Once replication works, you can change the DNS back to what it was. If you are not replicating over the weekend and have a somewhat zealous scavenging routine going, consider increasing the aging settings, or increase the frequency of replication. If you don't know what I'm on about, don't worry. ;-) -- Paul Williams Microsoft MVP - Windows Server - Directory Services http://www.msresource.net | http://forums.msresource.net Paul Williams [MVP], Oct 30, 2005 #2 Advertisements tommy Guest This did not work....
