You may not have access to the network switch, so this may not apply to you. Anyway, you can go to the network switch and grep the mac and ip address off it. It will even tell you which port the ip or mac came from.

One possible way to do this is to ping the broadcast address of the network that you are on. Then look at your arp cache with 'arp -a' (works on both Windows and *nix). As long as the number of hosts responding to the ping don't exceed the size of your ARP cache, the IP address you are looking for should be in the cache. -paul --------------------------------------------------------------------------- Evaluating SSL VPNs' Consider NEOTERIS, chosen as leader by top analysts!
