SYMPTOMS
When the Microsoft Message Queuing (also known as MSMQ) service in Microsoft Windows Server 2003 performs a remote read operation, it may return the second message in the queue instead of returning the first message.



CAUSE
A race condition permits client calls to occur out of order exists on the server side. This problem only occurs in Windows Server 2003 because the Message Queuing remote read code was rewritten in Windows Server 2003. The server side of the remote read operation now serializes the client remote read calls.



WORKAROUND
To work around this problem, perform the read operation from a local queue instead of from a remote queue.
