Michel,
Thanks for your reply but I do not wish to configure or install a proxy server. I want to find if someone who is not authorize to setup a proxy, setup one on the network.

Well, if you have some guesses/assumptions to the characteristics or flavor of the unauthorized proxy in *active* use, you can have measures like having a NetFlow reporting tool/RMON II probe alert you on certain traffic pattern (say, assuming all TCP port 3128 traffic are Squid Cache proxy) going over a certain rate or volume. For a proxy that's not talking much, what can you do? Sweeping port-scan your own IP ranges?
