Generally ICMP and Ping are useful for quickly checking if machines are up/down. The firewall of Windows 2008 closes ICMP replies by default.
You can enable the ping command with following steps:
1) Go to Start
2) Open a command prompt
3) Type in the following: netsh firewall set icmpsetting 8
To disable it again, execute the following command from command prompt:
~~~
netsh firewall set icmpsetting 8 disable
~~~
OR,
We can enable ping in windows server 2008 by the following method also:
~~~~
Goto Start >> Administrative Tools >> Windows Firewall with Advanced Security >> Scroll down to "File And Print Sharing (Echo Request - ICMPv4-IN)" (or v6 if you are using ipv6) >>Enable this rule.
