1. I think, you monitor the network traffic and see which authorized machines are generating the most of the traffic. And hen you can conclude who is running the proxy server on their machines.
2. Or you can use npulse to check all the machines in ur LAN and see which ports are open on these machines.
Thanks
Yash

Perhaps if you are on linux you can use nmap to scan your whole subnet and
output the scan to a text file then you can grep it for the word proxy (
means you gotta be root and do an -sV ) correct me if im wrong.
