#netstat -rn

Hi Prabhu,

I would do this.

1) Check whether there's a link on the NIC.
2) Use the console to check whether server is able to ping own IP address.
3) If pinging, try pinging the gateway.
4) If pinging, try pinging an IP from outside the subnet.

This should get you started.

Yes there is link in the NIC,and cable is also proper.
i am not able to ping the gateway but i am able to ping localhost.
and all the network configurations(mask/gateway) are correct, i am not getting why this server is not reachable
