SYMPTOMS
When you send transacted messages from a clustered Microsoft Message Queuing Resource Service by using Direct= ... syntax in the FormatName property, the messages may remain in the sender computer and may not arrive at the destination. Specifically, the connection is established but the messages are not delivered.

When you send direct or transacted messages from a remote (noncluster) computer to the same queue, the operation is successful. When you send from the same clustered Message Queuing Resource Service to the same queue by using syntax other than Direct= ... in the FormatName property, this operation is also successful.



CAUSE
When a client performs a broadcast to resolve its site and connected network, a Microsoft Message Queuing, also known as MSMQ, computer on a cluster may answer it by using the node's IP address; as a result, the answer does not reach the client. The client may fail to bind remote procedure call (RPC) listening ports to the necessary IP addresses, and therefore it does not accept messages from those addresses.



RESOLUTION
Warning 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 your operating system. Microsoft cannot guarantee that these problems can be solved. Modify the registry at your own risk.

This hotfix adds a new registry subkey of type REG_DWORD:

HKEY_LOCAL_MACHINE\Software\Microsoft\MSMQ\Parameters\StaticAddrRes

If the value of this subkey is set to 0 or does not exist, the client broadcasts when it connects through Remote Access Service (RAS) or whenever its IP address is changed. However, if this subkey is set to a non-zero value, the client never broadcasts and it assumes that its connected network and site remain static. It then uses the current registry values for this information.
