what kind of solution are you looking for? if you want to figure out what's generating those queries, check any system that's generating them; that'll hopefully help you locate the problem on all the systems. on your system, you can run wireshark/tshark or tcpdump and capture packets sent to your proxy, and analyze them.
Watch out for the Manners Taliban!
Isn't it amazing how so many people can type "linuxpakistan.net" into their browsers but not "google.com"?

Dear osama,
Salam,
