OOh i made it little confusing .
Actually what i mean to say is this.
"I start the Server .It loads the kernel and then start running services by its own"
whenever it starts the service of network for initializing the network interface and bonding it says the status as ok.
But when i try to ping the server from different machine it remains unpingable .
After few minutes it comes to the network.
Hope i made my point clear.
