I have Lenovo G580 laptop with Centos 5.9 installed in it. My machine is accessible by some machines in my network, but many machines(both windows and linux) are not able to access my machine. But they are able to connect if I ping them. No problems with firewall, subnet mask or domains.

Can you provide more details to your questions. For example, how are you trying to access your machine from other computer system on the network? What is your network setup, and subnet and such? –  shinjijai May 29 '14 at 14:03
your description hints at ARP problem somewhere en-route –  wmz May 29 '14 at 14:06
How are you pinging your machine, by name or IP address? –  MariusMatutiae May 30 '14 at 9:24
