MSDTC communication error while BizTalk connecting to SQL server. RRS feed

  • Question

  • Hi,

    I am getting the below error while connecting BizTalk to SQL server using WCF Custom  SQL Adapter. Bothe BizTalk & SQL server are on the same machine.

    Details:"System.Transactions.TransactionManagerCommunicationException: Communication with the underlying transaction manager has failed. ---> System.Runtime.InteropServices.COMException: The MSDTC transaction manager was unable to push the transaction to the destination 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. (Exception from HRESULT: 0x8004D02A)

    I have tried different combinations of Local DTC Properties settings (restarted the MSDTC and BizTalk host instance between each setting change ) , but the connectivity error did not resolved.  I have checked couple of forums but couldn't  work. Any help would be greatly appreicated.
