I've added all my location in and the removed the servers from the unknown location

If I have a problem with a machine not recognising a location or I miss a location.

Is there anyway of changing the location manually back to a defaul setting so I can then add in the new location and back to working operation?

I'm quite aprehensive that this has been turned on in my enviroment.

I've had to strip the client off a few machines already and reinstall.
