I have a remote PC with a Watchdog application running on it. This is monitoring the health of other applications runing on the PC, and if it detects a problem, will reset the PC. All applications are written in Visual c++, OS is XP home.

Is it possible to send a message over the network to the Watchdog app to instruct it to reset the remote PC?

Will FindWindow() work over a network (using the IP afddress of the remote machine), or is there another way of getting the handle of the Watchdog application?
