Q. How do I enable a system running Windows Server 2008 Server Core to be pinged?

A. To enable the firewall exception for the Internet Control Message Protocol packets used during a Ping operation, run the command

netsh firewall set icmpsetting 8
Microsoft has announced that this syntax might be depreciated in a future version of Windows and recommends the new "netsh advfirewall" syntax. Using the new syntax, the command would be

netsh advfirewall firewall add rule name=
   "ICMP Allow incoming V4 echo request"
   protocol=icmpv4:8,any dir=in action=allow
