Scans a class B IP network. You would need to be on the same subnet as them. depending on your network structure , e.g. switches, it will be very expensive to track and trace. If you are running switches you may be able to interogate the switches. Even then , they may end up using IPX (or any other protocol) on their laptops rather than IP so the only way to limit them is to bind the MAC address for each legal card to a switch port, assuming the switch supports this. hceers Dean >-----Original Message----- >From: Filipe Joel de Almeida [mailto:[EMAIL PROTECTED]] >Sent: Tuesday, April 23, 2002 10:54 AM >To: NT 2000 Discussions >Subject: RE: Network discovery > > >Well, I have found some tools that will give me a MAC address, but from >that, how can I know that machine's IP address.
