asumeing you know who's computer it is. i imagine you know what room its in etc... email all the other users of who and what room their in(othe contact info, ie phone number etc) , that their neglagance is preventing the network from operating correctly. if its soo bad emails dont work, time to start posting flyers... or somehting like that. point is. inform all the rest of the users who's responsible for it, and where they can be found... the problem will solve its self ^^
