I use the windows FTP command line client to do batch updates to external sites. On server 2008 I am getting the following error... 230 User <user name> logged in.ftp> dir200 PORT command successful425 Unable to build data connection: Connection timed outftp> quit421 No Transfer Timeout (600 seconds): closing control connection. I have made the changes suggested in http://support.microsoft.com/kb/323446. I can get a directory listing in IE but not from the command-line client. Interestingly, the command works fine on a Vista client sitting behind ISA 2006.

Dont worry. After much searching I found a registry hack: HKEY_LOCAL_MACHINE \ SYSTEM \ CurrentControlSet \ Services \ SharedAccess \ Parameters \ FirewallPolicy \ DisableStatefulFTP = 0

Hello Mike, Thank you for sharing the solution. I believe that other members will also benefit from your findings. BTW, you may use "quote PORT" to enforce the FTP client to use PORT mode. This will enable the FTP transport package come across the Windows Firewall.
