One of the resources created by the setup program is called the “Loftware Mirror Manager.”  This resource mirrors two registry keys that are used by Loftware.  The keys are “HKEY_LOCAL_MACHINE\SOFTWARE\Loftware, Inc.” and “HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\WatchDogNT”. In the event of a failover, any printers that you have configured or preferences that you have set are copied to the registry on the other node.

All Loftware applications require that the mirror manager be running. Furthermore, even if the mirror manager is running, you cannot invoke any Loftware applications on the node that does not own the quorum.  This guarantees that any changes that you make are picked up by the mirror manager and are made available to the other node in the event of a failover.  A warning message is displayed if you try to invoke an application that is not covered by the mirror manager.
