Red Hat 6 hung at Starting Red Hat Network Daemon.

I have a red hat 6 box, all i did to it so far was updated to 2.6.32-220 x86-64 and renamed the host via /etc/sysconf/network and rebooted. Now the box will not get past the Starting Red Hat Network Daemon section of booting. I can do a Ctrl-Alt-Del and it will reboot, but just goes back to hanging at the same thing. Does anyone have any ideas as to were to start with diagnosing this?

Thanks for the help in advanced.
