Hi - I do work for a school where there are about 100 computers on site that basically just connect to the internet, no true AD network. I received a call over the weekend telling me that as of last week there were some that were able to get online, and some that were not. For the ones that were not, I was able to connect to them remotely, but could not connect them to internet at all. The ones that could not connect we're getting a way different IP address out of the range on the router, telling me that there was some rogue device running dhcp, as if someone had plugged in another router somewhere on campus. How would I go about troubleshooting this WITHOUT having to go to each network jack on campus to make sure no device is plugged into it? Any suggestions would be helpful. Thanks!
