Quick DHCP Setup

I have to say that dhpcmgr(1M) is the kind of admin GUI that reminds
us why admin GUIs have a bad name and why I stay away from Windows.
It still thinks the world uses classful IP addressing? It took me a
while to get the thing to work at all.

I just want to quickly set up DHCP on a Solaris 10 machine to hand out
a network address to a DHCP client. The client is, literally, a black
box with just a network port in it. It's sending a DHCPDISCOVER packet
with a Host Name option set. I can't get the Sun DHCP server to respond
to it. When running in debug mode I see,

   43727d46: Datagram received on network device: qfe0(limited broadcast)
   43727d46: select_offer: hostname request for globalstar-03
   43727d46: name_avail(F): the DHCP server believes the IP address that corresponds to the requested host name is not managed by the DHCP server.
   43727d46: select_offer: name_avail false or no address for globalstar-03

However, I have an entry in /etc/hosts for globalstar-03 that falls
squarely into the range managed by the server. At least I see that
IP address listed in the dhcpmgr interface.

Does anyone have experience with these awkward DHCP tools Sun provides?
I'd like to get this up in a hurry.
