I’ve just finished building a couple of dedicated application servers for a client. One is for IIS and the other is for SQL. I was somewhat confused though that they did not respond to a PING command. A little digging into the firewall on the server showed me that by default the ICMP Response is disabled unless you have enable File and Printer Sharing. See below for the rule I had to enable to make it work.
Keep this one at the back of your mind for future application server rollouts.
