This message can mean lots of things, from the incorrect driver inserted 
to incorrect syntax in the ifconfig command.

Now, RH does things in its own special way, so I would suggest trying to 
configure/activate you interface with the GUI provided (run "neat" as 
root from a shell) and go from there.

If that doesn't provide any hints, check the scripts under 
/etc/sysconfig/network-scripts/ for something like ifcfg-eth0, to see if 
any of the parameters captured there is incorrect.

If you're trying to connect to a DHCP network, you can just do 
everything manually to narrow down the issue:

# ifconfig eth0 up
# dhclient eth0

If ifconfig complains, there is a driver issue. Check out 
/etc/modules.conf for aliases for eth0, and /var/log/messages for error 
messages from your NIC driver.
