FTP can use either Active or Passive mode. It affects the direction that the DATA connection is opened, and the ports being used: http://slacksite.com/other/ftp.html So, you may need to change your configuration, or force one or other mode, depending on the overall network setup.

IIS seems to configured correctly (I think), I can see port 21 open to the world via Shields-Up, tcpmon shows 21 is listening, FTP is set to use basic authentication. So it "looks" alright, but all attempts to connect fail. IE says "The page can't be displayed". Filezilla says "can't connect to the server". Ftp.exe<ftp://Ftp.exe> says "Connection closed by the remote host". I just can't get any reason why it's failing? IIS FTP says it's logging but there are no files. Can anyone think of any trick to get more useful information about why it's failing? Greg K
