Allowing pings in Windows Vista, Windows 7, Server 2008 and 2008 R2

Pings should just always be allowed - checking quickly whether a server is still running happens more often than a Ping Of Death attack!  The firewall will block them by default, so start an administrative Command Prompt and type:

netsh firewall set icmpsetting 8

Windows 2008 R2 and Windows 7 both whinge as below that you're using a deprecated command, but it still works.
