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 rpc server is 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....
