Server 2008 (or SBS 2011) FTP not working

As mentioned here http://connect.microsoft.com/WindowsServerFeedback/feedback/details/524831/default-ftp-firewall-port-21-rule-is-broken-in-windows-2008-r2

When you first setup ftp on server 2008 (or web server 2008 in my case) the default firewall rule seems broken. If you delete recreate the rule it seems to fix the problem- but there is a better way.

Fix for Broken FTP Server 2008

Run command prompt with admin rights and run the following:
sc sidtype ftpsvc unrestricted

Restart the ftp service with these commands:
net stop ftpsvc
net start ftpsvc

Now you should be able to connect to your server 2008 ftp sites.
