Check /etc/sysconfig/network-scripts and verify that that the ifcfg-DHCP
(VERY bad name...see below) specifies "DEVICE=eth0:3".  If not,
dhcpclient won't work since no DEVICE has been defined.

The scripts in /etc/sysconfig/network-scripts should be named after the
interface it affects--NOT the protocol used to define its IP address,
e.g. "ifcfg-eth0:3", NOT "ifcfg-DHCP".

In each file is a "DEVICE=" definition which should also specify the
device.  dhclient depends on the device name in
/etc/dhclient/dhclient.conf to specify its parameters (see the
"interface" specification in "man dhclient.conf").
