Hi Michael, I'm not sure of your difficulties but I have experienced this same issue going through ISA and it's not to all sites. So, what I do from the command line is test the ftp 111.111.111.111:21 and it seems to work. So, I'm guessing that it has something to do with the IE service pack. I have one machine with IE 5.5 on it and it works well.

I had FTP Explorer, Cute FTP and IE configured on a number of servers and workstations to get FTP access. I had them configured with Passive Mode checked. They have worked like this for over 12 months. Now all attempts at using FTP fail. I get the error when using IE ISA Server: extended error message: 200 Type set to I. 500 Illegal Port Command When I attempt to connect to an FTP site via a proprietary ftp program I get: STATUS Socket connected. Waiting for welcome message..... Then the program hangs indefinitely I have changed the administrator password in the recent past, but I can't see how this would affect things. Is there some folder that needs specific permissions for FTP to work? Anyone got any ideas please! It is a real pain since so many sites with device drivers and software for printers etc are now only ftp.
