There's always the alternative of just using a static IP setup, and fill in
the IP and gateway with what you *know* to be correct.

/var/log/messages should be what he's after.

In /var/log/messages the evil people who are Redhat have made it output the
deeply confusing message:

ifup: Determining IP information for eth0...
dhclient: DHCPREQUEST on eth0 to 255.255.255.255 port 67
dhclient: DHCPACK from 192.168.0.1
NET: /sbin/dhclient-script : updated /etc/resolv.conf
dhclient: bound to 192.168.0.2 -- renewal in 854 seconds

Quit the inane distro bashing Dave, it's not [wylug-]helpful.

Do you want to have a look through /var/log/messages (searching for eth0
should find the bits we're interested in)?

Is it definitely configured correctly?  What is in
/etc/sysconfig/network-scripts/ifcfg-eth0?

Indeed not.
