MSMQ independent clients can move to other CNs and sites without manual reconfiguration. When a client connects to the new site, all messages that were sent to the client while it was disconnected are rerouted from the client's previous site to the client at the new site. Messages that are sent to the client while it is connected at the new site are routed directly to the client at the new site. However, if the client specifies a new site before disconnecting from the network, messages that are sent to the client while the client is disconnected are routed directly to the new site before the client reconnects.
When an MSMQ independent client moves to a different site, its InRS and OutRS settings are ignored (when routing messages) until the client returns to its original site. You can reconfigure InRS and OutRS settings for the independent client while it is out of its original site, but the InRS and Out RS settings are still ignored. When the independent client is returned to its original site, InRS and OutRS settings are again used when routing messages.
MSMQ does not support mobile servers. To move a server to another CN, simply use MSMQ Explorer to change the server's CN assignments. To move a server to another site you must uninstall the server and then reinstall it in the new site.

On MSMQ independent clients, the MSMQ service sends out a broadcast when it starts, and monitors all replies. If a site controller other than the independent client's current site controller replies, and if the new site controller can communicate with the site controller in the independent client's original site, the independent client connects to the new site. If you have more than one site controller in a broadcast segment (for example, in an MSMQ lab) more than one site controller can reply to the independent client's broadcast. If one of the site controllers that replies is the controller for the independent client's current site, the independent client does not connect to another site. |
