SYMPTOMS
After you move a client computer from one site to another, you may experience delayed responses when Microsoft Message Queuing, also known as MSMQ, does the following:
 * Opens queues
 * Performs lookups
 * Updates its Message Queuing objects



CAUSE
Windows 2000 Service Pack 2 (SP2) contained a fix for the Message Queuing service that reduced the load on domain controllers. This fix incorrectly suppressed the building of the site servers list after a change of the address of a mobile client. By not updating the server list, a mobile Message Queuing client continues to go to its previous site server for any queries or updates until the next scheduled refresh interval. Depending on the topology, this may result in a lengthier time for the Message Queuing service to:
 * Access Active Directory.
 * Opens queues.
 * Performs lookups.
 * Perform updates to the Message Queuing configuration of that computer.



RESOLUTION
In the following resolution, the query to rebuild the server list is performed whenever the IP address for a Message Queuing computer changes.

A supported fix is now available from Microsoft, but it is only intended to correct the problem that is described in this article. Apply it only to computers that are experiencing this specific problem. This fix may receive additional testing.
