TransactionScope error: Communication with the underlying transaction manager has failed, works fine when reboot RRS feed

  • Question

  • This has been bothering us for a long time, every now and then it starts acting up and when we reboot the machine it works fine for a while. Checked the DTC Logs it just says "transaction being aborted" nothing else.

    Any idea what should we check ? here is the full stack trace and error message.

    System.Transactions.TransactionManagerCommunicationException: Communication with the underlying transaction manager has failed. ---> System.Runtime.InteropServices.COMException: The MSDTC transaction manager was unable to pull the transaction from the source transaction manager due to communication problems. Possible causes are: a firewall is present and it doesn't have an exception for the MSDTC process, the two machines cannot find each other by their NetBIOS names, or the support for network transactions is not enabled for one of the two transaction managers.

  • Hi Fahad,

    Looks like you have communication poblems between the two machines participating in the transaction.

    Have a look to the following article. 


    The first thing I would do is to check you have enabled the Allow Network transactions setting in both DTCs, also check that you can ping from one machinge to the other using the machine name not the IP.

    Let us know if you still don't manage to make ti work.

  • Thanks for the reply. Outbound and Inbound Network DTC is allowed with no authentication required. Both machines can see each other by name.

    Please note that this issue is intermittent, happening between my dev machine and database server and when start happening, the only solution is to reboot my machine.

  • Have you checked if when the DTC start failing the DTC service is running? Maybe it has crashed and stopped, and so when you restart the machine it start working again.

    I would also check the DTC logs to see if you can see anything odd there. Have you checked the Event Log to see if the DTC service is logging something?

  • I did not notice if DTC Service crashed. Next time this happens I will do that. I did check the Windows Event Log, nothing recorded.

  • Ok it failed today with same error. Event Log reported nothing. Service status says Running.

  • Hey Fahad,

    Is the MSDTC log saying something? You can find how to check it looking at the link I suggested before.

  • Looks you are having problems with the RPC Endopoint Mapper. Can you have a look at the following link and see if it fixes your problem?


    Which version(s) of windows are you using?

    Also seems like a similar thread has been covered in the forums before:


    Which also points to this other kb:


    Let me know if it works!
