I have the same issue of not being able to download files through ftp b/c of ISA Server. From looking at the website it appears that a number of other people do too. I phoned Microsoft Product Support Services as you suggested, but the technician I spoke with was not familiar with this particular hotfix and wanted to charge me $245 to connect me to someone at Microsoft who could give me the hotfix #! Could you send me the name/number of the fix please? They won't give me ISA Server SP1 beta either without this hotfix number. To make sure we are on the same wavelength, here is more detail on my company's issue with ISA server: Whenever anyone tries to download a file from a site the download now fails if ftp is involved. I can download files fine thru FTP from a computer not behind ISA server. For example I went today to 3com and tried to download a NIC driver. I started at a http site but the download involved an ftp site and so the site timed out. I found a workaround from an article on this issue at google groups. I put in the ftp site in the url field directly and then on the page that showed the download I right clicked the file and chose "copy to folder." With this method the ftp download worked. But if I just doubleclick on the file to download while at the http site and do a normal download (that required Internet Explorer changing over to the ftp site in the background), the download fails. Thanks for your help! FYI, the article by Tom Schnider on Internet Explorer and FTP is interesting but does not resolve this issue. http://www.isaserver.org/shinder/tips/ie_and_ftp.htm Richard Boyce seerjboyce@xxxxxxxxx
