Well, my first question is why does it matter?
But, to answer your question, I suspect that you have an entry in
/etc/hosts on the first machine that looks like this:
192.168.0.20 hporau1 #OR
192.168.0.20 hporau1.fantasyentertainment.com hporau1
and on the second machine you don't.
Another possibility is you have the entries in /etc/hosts on both
machines, but /etc/nsswitch.conf is different on the two hosts. The first
one probably looks something like:
hosts: files dns
and the second probably has the order reversed.
There are probably several other explanations that I haven't thought of
off the top of my head... for example you may also be using NIS (you'd
know it if you were, unless you just inherited administration of these
boxen and the original admins are all gone). Host name resolution is kinda
complicated.
