By default, Windows Server 2008 is configured to block all incoming Internet Control Message Protocol (ICMP) echo requests. You can enable the echo requests by making a configuration change to the Windows firewall using the following two methods.
1. Open the command prompt and type the following command “netsh firewall set icmpsetting 8”.
2. Open the Windows Firewall with Advanced Security. Navigate to the inbound rules and enable “File and Printer Sharing (Echo Request – ICMPv4-In)”.
