Colleagues are skipping around the office with smiles on faces…until…duh duh daaa! If you haven't already done so, install the latest Windows Server Support Tools on all your production systems. (All the utilities I describe in this article are Windows Server Support Tools.) But first you need the experience of carefully performing each step, to ensure that you don't jump to the wrong conclusion or have to go back to a previous step. verify the network connectivity first and then ports on the firewall.
After an RPC bind failure has occurred, a cleanup routine will run to clear the destination DCs queue from that same source DC. Type "portqry -n
Make sure the target DC can resolve the source DC. DomainDnsZones passed test CrossRefValidation Running partition tests on : Schema Starting test: CheckSDRefDom .........................

Error 1722 The Rpc Server Is Unavailable Services Msc It's also listening on ports 389, 3268, and 3269.
If you don't think you're getting enough detail from the directory log, go to the HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\Ntds\Diagnostics subkey and enable NTDS logging. For example, you can test all the ports at the same time by using the Portqry tool with the -o switch. If the DC in question is in a child domain, the PDC looks to a DC in the root domain as a time source, and these DCs in turn look to their explanation Troubleshooting Authentication Verify that authentication is working correctly by checking for Time skew, UDP Fragmentation or an Invalid Kerberos Realm.
It can also be caused by antivirus software with many of them sporting a new feature called "network traffic protection," which can efffectively block necessary AD traffic.

Microsoft's PortQry tests specific AD ports and the ephemeral ports, and the required responses from the services on the required AD ports it specifically scans for. http://supercgis.com/rpc-server/replication-generated-an-error-1722.html We've determined the problem to be that Kohai's DNS CNAME is missing. The DC named Sandan is in the Branch site, connected to the Hub site by a site link with a replication interval of 15 minutes. When the application registers with the EPM it will indicate the IP address and TCP port that it is listening on. Rpc Server Is Unavailable Server 2012 R2
And finally, if you receive errors that indicate the DC hasn't replicated for a period longer than the tombstone lifetime, you can stop trying to troubleshoot. Additional Troubleshooting: If the above do not provide a solution to the 1722, then you can use the following Diagnostic logging to gather more information: Windows Server 2003 SP2 computers logs Data needed to troubleshoot the issue: Identify the client and server computers reporting the RPC error. http://supercgis.com/rpc-server/replication-error-1722.html If everything looks good on the home front—that is, if NetDiag and DCDiag didn't reveal any OS or directory service–related errors—it's time to start looking at replication.
Which key value to increase logging on depends on the area you're investigating (e.g., Knowledge Consistency Checker, Name Resolution, Replication Events).

Because DNS can't resolve Kohai via its CNAME, replication can't occur. Other Tips First, be patient. For information about network troubleshooting, see Windows Help. http://supercgis.com/rpc-server/replication-failed-with-error-1722.html Knowledge base article 313190 - "How to use IPSec IP filter lists in Windows 2000" provide details about where to check these settings and more information about their impact. 2.

Phase 4: RPC Communication: RPC Communication is the act of making RPC requests to the application endpoint and receiving RPC responses from this application. How could a language that uses a single word extremely often sustain itself? Please check the machine.

It lays out RPC basics really quickly and then moves on RPC errors. Finally, verify the protocol that the directory service uses and determine whether the DCs are authenticating correctly with one another.
