Is there a possibility that in the environment you're working within, there's one *right* nameserver, and all others have their queries blocked? Or that all HTTP requests have to be run through a local proxy, and all other requests are blocked?
Outbound blocking by a firewall seems like a huge bet as to why things might be looping.
