IIS FTP login fails after Windows platform update for Server 2008 R2
I had recently enabled FTP access to the ClipFlair Gallery to easy its maintenance during development and after the Windows Server 2008 R2 platform update last night (together with release for Internet Explorer 10), the FTP login stopped working.
To fix it, from a command prompt with administrator rights (Start/Find, type Command and right click the Command Prompt item found to open as administrator), give the command:
netsh advfirewall set global StatefulFtp disable
It’s easy to copy-paste it from here and right-click on the command prompt title bar, then select Edit>Paste (no shortcut key for that unfortunately), then press the ENTER key and it should reply “Ok”.
Had done this before, but seems the platform update re-enabled filtering for Stateful FTP (also note that at http://www.iis.net/learn/publish/using-the-ftp-service/configuring-ftp-firewall-settings-in-iis-7 it seems to erroneously say that you need to use “enble” instead of “disable” when not using SSL).
