IP address conflicts

[Tim Aslat]

Hi All,

I have an annoying situation in a school I do casual work in their IT
department.  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?

Cheers

Tim
