Event ID 2159 MSExchange ADAccess Process MSExchangeFrontendTransport.exe (PID=8648). Configuration object CN=Interop RGC,CN=Connections,CN=Exchange Routing Group (DWBGZMFD01QNBJR),CN=Routing Groups,CN=Exchange Administrative Group RRS feed

  • Question

  • We are in co-existence with Exchange 2010 and 2016.   I'm getting lots of warnings in event viewer in administrative events about MSExchange AD Access   they all seem to reference routing groups connector.    I'm trying to figure out how to resolve these errors.   When I do a Get-RoutingGroupConnector I get the below error.

    This error seems pretty consistent.

    Any idea how to solve would be great!!

    Process MSExchangeFrontendTransport.exe (PID=8648). Configuration object CN=Interop RGC,CN=Connections,CN=Exchange Routing Group (DWBGZMFD01QNBJR),CN=Routing Groups,

    Process edgetransport.exe (Transport) (PID=9824). Configuration object CN=Interop RGC,CN=Connections,CN=Exchange Routing Group (DWBGZMFD01QNBJR),CN=Routing Groups,CN=Exchange Administrative Group 

    Process MSExchangeDelivery.exe (PID=8664). Configuration object CN=Interop RGC,CN=Connections,CN=Exchange Routing Group (DWBGZMFD01QNBJR),CN=Routing Groups,CN=Exchange Administrative Group 

    Process MSExchangeSubmission.exe (PID=8528). Configuration object CN=Interop RGC,CN=Connections,CN=Exchange Routing Group (DWBGZMFD01QNBJR),CN=Routing Groups,CN=Exchange Administrative Group

  • Hi Jeff,

    Is there Exchange server 2003 used in your environment before?

    Generally, the routing group connector is used to send and receive messages between Exchange 2010 Hub Transport servers and Exchange 2003 bridgehead servers. 

    If there is no Exchange 2003 in your environment now, it is safely to remove the RGC object now. Please use the Remove-RoutingGroupConnector cmdlet to remove a routing group connector then delete it from: CN=Interop RGC,CN=Connections,CN=Exchange Routing Group (DWBGZMFD01QNBJR),CN=Routing Groups,CN=Exchange Administrative Group 

    Then check if the issue can be fixed.

  • Hi Winnie

    I could not use the Remove-RoutingGroupConnector initially because they were both named the same name Interop RGC.   So I deleted the one with all the errors above first and then I was able to delete the original one using the Remove-RoutingGroupConnector command.   Since I completed the command I have not seen one MSExchange AD Access error.  It's been two hours since I removed these routing groups and I have not seen one of these warnings.  They were hitting every 15 minutes.   Thank You very Much!!!
