Microsoft has confirmed that this is a problem in the Microsoft products that are listed in the "Applies to" section.
This problem was corrected in Windows XP Service Pack 2.
This problem was corrected in Windows Server 2003 Service Pack 1.
In this scenario, there is one sender and two receivers (Receiver A and Receiver B). Receiver A connects to a network by using a virtual private network (VPN) connection. The sender sends messages successfully. Receiver A disconnects from the network. Receiver B connects to the network and obtains the IP address that was previously used by Receiver A. Receiver A may also reconnect and obtain a new IP address. The sender continues to send messages that are intended for Receiver A to the IP address that is now being used by Receiver B. The sender does not retry name resolution because the previous result was cached. Receiver B rejects the messages, but the sender continues to send messages to Receiver B. You must restart the Message Queuing service on the sender's computer to resolve the problem.
Registry changesWarning Serious problems might occur if you modify the registry incorrectly by using Registry Editor or by using another method. These problems might require that you reinstall the operating system. Microsoft cannot guarantee that these problems can be solved. Modify the registry at your own risk.
In addition to applying the appropriate update, you must set registry parameters on the receiver and on the sender. The following registry change is required on the receiver side so that the receiver will release a session if it receives a message for a non-local queue. This change means that the receiver will not return a session acknowledgement and the sender will close the session a short time later. It is standard on the sender side to close a session if an acknowledgement is not received in a specified time-out period. The sender then tries to reestablish a session. Follow these steps, and then quit Registry Editor:
The following registry parameters are also required to flush the DNS and NetBIOS name resolution caches. Otherwise, an IP in the cache may be owned by a different computer:
