I have a network set up, here at home. This network is made from a proxy server using ISA (Microsoft Internet Security & Acceleration). There is a problem downloading a file with the systems connected through the server (client systems), whenever one of these systems is downloading a file, the download process would start for a couple of seconds and then it would say the download is done, even though the download is interupted because, whenever i open the downloaded file, it says the file is corrupted because the download bar was stopped almost halfway through. I ran several anti-virus programs and they couldnt catch anything, i also ran ad-aware/spybot, nothing was found. I am thinking it might be a bug from ISA. please help, thanks.

How about removing the ISA server temporarily...hooking one of the client machines directly to your internet connection and try the same file again. That will tell you if the problem lies with ISA or somewhere else.

I connected it directly to the router and i didnt have a problem with downloading. So i know that the problem is coming from the sever, any ideas on what i should do in order to fix it though?
