  • Closed as program error.

Error description

  • WebSphere MQ V7.1 runs on Windows 7, Vista or Server 2008 and it
    participates in transactions coordinated by MSDTC (Microsoft
    Distributed Transaction Coordinator).
    The MSDTC service account is "NETWORK SERVICE".
    
    When running a COM+ server application, it fails with error
    MQRC=2354 (MQRC_UOW_ENLISTMENT_ERROR).
    
    In addition the following error message is written in
    AMQERRxx.LOG:
    ================================================================
    AMQ8074: Authorization failed as the SID 'S-1-5-20' does not
    match the entity 'MACHINE_NAME$'.
    
    EXPLANATION:
    The Object Authority Manager received inconsistent data - the
    supplied SID does not match that of the supplied entity
    information.
    ACTION:
    Ensure that the application is supplying valid entity and SID
    information.
    ================================================================
    

Local fix

  • 1. Replace "NETWORK SERVICE" account of MSDTC service with
       another account.
    2. Set +connect authority for the account of MSDTC:
         setmqaut -m qmgrname -t qmgr -p MSDTC_account +connect
    

Problem summary

  • ****************************************************************
    USERS AFFECTED:
    Users of MSDTC as a transaction coordinator on Windows 7, Vista
    or Server 2008.
    
    Platforms affected:
    Windows
    
    ****************************************************************
    PROBLEM SUMMARY:
    The user name returned by the operating system for a process
    running under the "NETWORK SERVICE" user changed in Windows 7,
    Vista and Server 2008 to "MACHINE_NAME$" where MACHINE_NAME is
    the name of the machine the process is running on. This caused
    MQ authority checking to fail for the MSDTC process.
    

Problem conclusion

  • MQ has been modified to recalculate the user name from the
    returned SID, when the "MACHINE_NAME$" user name is returned.
    The SID correctly resolves to "NETWORK SERVICE" and results in
    the same behaviour running on earlier Windows versions.
