Did someone bring in a router from home that hands out dhcp? What you can try to do is obtain an ip address and then look at the default gateway and find the mac address by looking at the arp table. You can then do a show mac-address-table | in and then keep tracing it to the other switches until you find where it is originating from.


You can also setup dhcp snooping and shut that down.
