there is your problem right there. change the onboot from no to yes, then as root run:
# service network restart
that should get you up and running provided you are in a DHCP LAN. for some reason the default for ethX in RHEL is now off. just make that adjustment and from now on as long as the cable and LAN are functioning including the DHCP server, you should be ok.
