I have a new Windows 2008 server with IIS7. When I connect to the ftp in active mode, it works fine. In passive mode, it connects, but then times out trying to get the directory listing. I tried disabling both firewalls, but it didn't help. I've tried this with difference client machines and different ftp client software, with no change. Any ideas?
In the command prompt of the server, enter these two commands to open the firewall:
netsh advfirewall firewall add rule name="FTP (non-SSL)" action=allow protocol=TCP dir=in localport=21
netsh advfirewall set global StatefulFtp enable
In Amazon EC2, you also have to set up a security group to open the passive ports, such as 1025 to 7000.
I had the same issue using filezilla ftp server. Active connections worked but passive didn't... I solved it by adding FileZilla server.exe ( in the program files folder ) to the "exceptions list" of windows firewall. Then everything worked. Just goes to show you ... RTFM.
You can actually try following the article Out Of Band FTP 7 shows "Operation timed out".
I'd disable the IIS FTP Server and switch to single-port SFTP instead using "NULL FTP Server" . It's more secure and only requires a single port to be opened unlike the old style FTP protocol.
