I think there is some confusion. Either on my part or some of the other 
posters. The issue is not they are getting out of the network through an open 
proxy, at least I hope not, because if thats the case then they have bigger 
problems with network config.

The issue is that once they go out their proxy they hit another one to 
obfuscate where they are coming from. However, by going thorugh the open proxy 
they danger themselves up to information leakage/interception which was the 
original concern.

Perhaps the original poster can clarify?

I haven't looked too deeply into this. If the corporate is using windows 2k/xp, 
you could consider setting the GPO to restrict modification of the INNET 
settings. (technet.microsoft.com/en-us/library/bb457144.aspx). Of course, this 
still doesn't stop cgi/web-based proxies.
