Network IP Conflict

We currently had a client that plugged in a router into their network without any authority that caused an IP Conflict and just so happened to be the sam IP as their router IE: 192.168.1.X which took out Exchange and a lot of users accessing internet etc. Is there any way to implement onto our Switches(ProCurve Switches) to disable any new IP device especially if it is a conflict.

Normally it's possible to disable or shutdown the unused ports/interfaces at the switch. But that solution is not very flexible, because if you want to connect a new network device, you have to activate this port again.

You could statically assign the ARP entry for the actual router on the switch.
