I am running a fully patched Fedora 21 system.  We are trying to give it

valid.

The DHCP server is like Win2008 Server R2.

I don't see that as possible unless the F21 machine has multiple NICs
and the software is reassigning names on each boot. Not likely, but if
it does, you could tell udev to always assign one of the NICs as a fixed
name (em1, eth0, whatever) via a udev rule, then make sure that's the
NIC which the dhclient runs on.
