Steel City Phantom

I developed a file managment and distribution system in C# a few years
ago. Its main file types that it distributes are MP3 files and other
audio formats (based on how the client wants to recieve it). several of
those clients upgraded to XP SP2 and can no longer download files. They
get a HTTP header, because they recieve the file name which is in the
header, but when the file download is finished, they have a zero length
file on the HD.

The way the download system is written, the client clicks on the link
that opens in a new window (via a target on the anchor tag), That ASPX
page does some security checks to validate that they are allowed to
download the file, creates the audit entry, and then opens the file and
sends it to the browser as a stream.

The problem seems to exist in both IE and Mozilla so it seems to be an
OS issue. we tried disabling the firewall on the XP machine and it made
no difference. Did M$ sneek some kind of digital rights managment
system that im not aware of?

any other ideas on what the problem could be?
