SYMPTOMS
After you apply Windows 2000 Service Pack 2, you may receive the following error message when you use Microsoft Message Queuing, also known as MSMQ, 2.0:

MQ_ERROR_SERVICE_NOT_AVAILABLE (0xc00e000b)



CAUSE
This error occurs because calls to MQGetQueueSecurity for private queues and for direct format names fail. These calls fail because the output buffer pointer is NULL. A change in the compiler options does not allow you to use a NULL output buffer for remote procedure calls. This issue may affect any applications that directly use this functionality.



RESOLUTION
This problem is resolved in Windows 2000 Service Pack 3.



STATUS
Microsoft has confirmed that this is a problem in the Microsoft products that are listed at the beginning of this article.
