Error description

  • IIS application fails to remotely connect to a queue manager
    and throws Win32Exception with access denied error on an
    OpenProcess call
    
    Exception Reported for the first time :
    System.Reflection.TargetInvocationException: Exception has been
    thrown by the target of an invocation. --->
    System.Reflection.TargetInvocationException: Exception has been
    thrown by the target of an invocation. --->
    System.ComponentModel.Win32Exception: Access is denied at
    System.Diagnostics.ProcessManager.OpenProcess(Int32 processId,
    Int32 access, Boolean throwIfExited) at
    System.Diagnostics.NtProcessManager.GetModuleInfos(Int32
    processId, Boolean firstModuleOnly) at
    System.Diagnostics.Process.get_Modules() at
    IBM.WMQ.CommonServices.TraceEnvironment() at
    IBM.WMQ.CommonServices.CreateCommonServices() at
    IBM.WMQ.CommonServices.TraceEnabled() at IBM.WMQ.MQBase..ctor()
    
    This connection, however, works locally because
    authentication/impersonation works differently when connection
    is local vs when browsed from a client.
    

Local fix

  • Granting "Query process information and read process virtual
    memory" rights to the impersonated user so that OpenProcess
    succeeds.
    

Problem summary

  • ****************************************************************
    USERS AFFECTED:
    Users of IIS applications that remotely connects to Queue
    manager
    
    Platforms affected:
    Windows
    
    ****************************************************************
    PROBLEM SUMMARY:
    WebSphere MQ client code issues an OpenProcess call on itself.
    However, an IIS application with impersonation turned ON does
    not have the required security privileges to issue OpenProcess
    call on itself. Hence the application throws Win32Exception with
    access denied error.
    

Problem conclusion

  • WebSphere MQ client code has been modified such that the
    Win32Exception is handled gracefully.
