redhat72 comes with dhcpcd as the dhcp client.(not that that matters for
this)

edit your /etc/sysconfig/network-scripts/ifcfg-eth0 (or whatever your
interface name is) and make it say:

DEVICE=eth0
BOOTPROTO=dhcp
ONBOOT=yes

or you can ifconfig down and ifdown the interface and run dhcpcd from the
command line.
