I have an ASP.NET app running in IIS that is hosting files but it blocks all access to *.upd files and yields a http 404 when i try to access them.
If I turn on directory listing it lists the file but I can't download it...
Is there someway to fix this?
You have to configure IIS to serve your file type as it won't serve unknown ones: http://support.microsoft.com/kb/326965
