  • This isn't programming related - it's down to firewall, network edge technologies, etc. – Damien_The_Unbeliever Apr 21 '12 at 16:43

    That's why I've voted to close with a redirect to serverfault. – Damien_The_Unbeliever Apr 21 '12 at 16:49
  • http://security.stackexchange.com/a/22713 blocking ICMP isn't necessarily a great idea, it is used to make TCP/IP networking work properly. Only a couple to a few of the ICMP protocols are actually a security problem, and ping isn't necessarily one of them. – Craig Tullis Oct 22 '13 at 05:39

Go to Start → Administrative Tools → Windows Firewall with Advanced Security → Inbound Rules → File and Printer Sharing (Echo Request – ICMPv4-IN) → right click and select Enable Rule.

My application now works fine and when I try to ping my server I do not receive any response.

    This didn't work for me until I also changed that rule's setting from "Allow" to "Block the connection". – WilliamK Jun 19 '13 at 23:33

Using the solution provided by Satinder, you should further refine the scope of which computer/server and/or IP range(s) can Ping your server.

That way, the public can't ping your server but maybe you or certain computer on your network can get to it in case you need a quick check on connectivity.
