In the last days I found that it someone from my network, which is not allowed to access internet, puts the same ip and mac address, as a computer that is allowed to access the internet, the OS doesn’t report an ip or mac conflict on the network. The result is that 2 computers with she same settings gets access to the internet.
I had downloaded the keiro winroute firewall, because if the user autentification, but this features didn’t solved my problem because as time as the allowed user is logged, the other one can use the internet.
The other problem caused by this ip and mac cloning is the pour network performance.
Please help. Any ideas will be appreciated. Thx, and excuse my bad English.

first of all, its not possible to use same ip and mac at same subnet and gain access to network with 2 comp at same time... it just cant work. For that to work u need some kind of NAT technique. mabye it can be done with some hack utility but i have never heard of such tool/technique.
For ur problem with trace the computer, just look up mac address in mac table at ur network equipment. I can be done in different ways depending on what kinda network components u use. then ur find the port its connected to. if u use hubs its abit harder but atleast u can find the broadcast domain it resides on..
