Thanks but I do not think I can use that approach because I do not have the  ISA clients installed I have configured the WPAD file for  autodiscovery.

PLease let me know if this would work without the clients installed or if you have any other ideas.

There are plenty of downloadable filters that can help solve this problem.  The GFI one is good.

GFI Download Security will allow me to block files, However I was hoping for a more cost efective (FREE) solution.
I do not know if the rest of you have to deal with a no budget attitude but that is what I am up against constantly.
