Like what? Not let you use your network? So then anybody who can start up a "sniffer" can instantly blow away everyone else's ability to use their network?

Say what? This would basically make all "sniffer" products worthless. If I am trying to debug network problems by capturing packets, and my presence on the net *changes* how the other machines are acting, then it would be poor debugging tool, wouldn't it? >How about requiring ALL Macs to run Responder, and have a central >monitoring program look for and log Macs that have gone "off air" >(Responder not responding). Except that there are myriad reasons why macs go "off air"... cmc
