Couldn't connect to Internet

I have installed fedora core 7 in my system. When I try to activate the network card it says "Could not determine IP address for eth0...failed".
Please give me suggestions?

do the following checks( you should be root)
->run the command ifconfig
see weather u have a valid ipaddress assigned
->open the file /etc/network/interfaces, check what all interfaces you have defined and if you are giving a static ip or taking from dhcp. you can give a static ip address also.

->modify the file if required and run these commands

->ifup eth0

->ifdown eth0

->ifup eth0

see the man pages of the command if you are stuck in between
