Yeah, I'm guessing the aforementioned device does send broadcast packets. What I'm wondering is by what protocol does it do so, why does XP choose to pester my users about it, and how do I kill that kind of traffic on the LAN?

I'm not asking this because I'm looking for help for the device itself. That's handled elsewhere. I'm just asking... today... right now... how do I kill this traffic on the LAN so that the device can still work, but work quietly without pestering my users? What protocol does XP use to do this irritating crap?
