What is ping ?
Ping verifies IP-level connectivity to another TCP/IP computer by sending Internet Control Message Protocol (ICMP) Echo Request messages. The receipt of corresponding Echo Reply messages are displayed, along with round-trip times. Ping is the primary TCP/IP command used to troubleshoot connectivity, reachability, and name resolution.
If you want to enable the ping /icmp on a windows 2003 or windows 2008 server then follow the below steps :
For Windows server 2003 :
Go to start >> run >> cmd >> netsh firewall set icmpsetting 8 enable
For Windows server 2008 the netsh firewall has been depreciated and you need to use netsh advfirewall firewall
Go to start >> run >> cmd >> netsh advfirewall firewall add rule name=”ICMP Allow incoming V4 echo request” protocol=icmpv4:8,any dir=in action=allow
That’s all you are done.
