Im not sure where to put this, but i think it might live here.... but here goes
We have some students with there own machines on the network, but what seems to be appearing is that we are getting multiple MAC address on a single switch port.
We have disconnected these users from the main network, but when we go and have a look at the machine, all seems to be fine, no special piece of software, and AV is up to date and a full scan brings up nothing.
So we are a bit stumped, and unsure if this is a hardware fault or an virus or trojan which is causing this...
Any help would be great
