There are a number of individuals within the system who think it's funny to allocate an IP address on a workstation identical to the network's proxy/web/mail servers. What I'd like to know is, would there be any way of preventing this short of spending quite a lot of money on managed switches an the like? I'm unable to restrict access to settings on the machines, as they are notebooks owned by the students/staff and could be legitimately plugged in anywhere in the network. Unfortunately solitary confinement on bread & water, or public floggings aren't an option. Any suggestions?
