So I'm told that today on our LAN a bunch of XP users got a little bubble popping up in their system tray saying "A new device has been added to the network <ip address>".

I happen to know what the device was, but I'm not going to say because then I'd have to kill you.

I want to make sure this doesn't happen each time I plug the device into the network. What irritating bloddy feature needs to be turned off so this crap doesn't happen?
