Replication issues between DCs-(1722) The RPC server is unavailable RRS feed

  • Question

  • Hello Folks,

    How to identify and troubleshoot the replication issue is because of Network,Port,Switch or Firewall.

    Is it like 1722 is always  because of some sort of changes at Network layer and how to verify network traces like what should be checked in network monitor to isolate the cause.(in my personal experience we ran into replications issue due to some or other kind of changes happened from network side)

    I am receiving following error while running dcdiag /test:replications and repadmin /replsum * 

    Experienced the following operational errors trying to retrieve replication information

    (1722) The RPC server is unavailable

    DCDIAG result

    DsBindWithSpnEx() failed with error 1722,
    The RPC server is unavailable..
    Got error while checking LDAP and RPC connectivity. Please check your firewall settings

    failed test Replications

  • Hi,

    Following the error , it seems that the network flow is opened between domain controllers or network issue.

    You download and use the PortQryUI tools from Microsoft site to check the network flow between your domain controllers.
