In order to clarify how the rite works please refer to page 144 in WtA. 

The book states you must know the target’s name (True Name, Right name, common name if long associated with person). It also states you only get the general location, never its exact location, for this purpose on the Mush, general is defined as a city db # where the exit to whatever location the target is in can be found. 

This rite should only be started when the target is online, so that proper IC calls for things like awareness, danger sense, Sight from Beyond may be taken into effect by the judge for the Target.
