Stan,
You may also have to set the option dhcp-client-identifier in the
/etc/dhclient.conf file. The value should be the MAC address of the
interface you are requesting the DHCP address on. I think this is
something that the Microsoft DHCP server expects.
E.g.
interface ep0 {
send host-name andare.fugue.com;
send dhcp-client-identifier 1:0:a0:24:ab:fb:9c;
}
-mark

Yes, you are right. I learnt something new here :)
So, I believe this is what we are looking at:-
send { [option declaration] [, ... option declaration] }
The send statement causes the client to send the specified
options to the server with the specified values. These are full
option declarations as described in dhcp-options(5). Options
that are always sent in the DHCP protocol should not be specified
here, except that the client can specify a dhcp-lease-time option
other than the default requested lease time, which is two hours.
The other obvious use for this statement is to send information
to the server that will allow it to differentiate between this
client and other clients or kinds of clients.
So it would be something like
send host-name andare.fugue.com;

In a correctly configured $MS environment the DHCP servers and DNS servers
are twins of each other. The DHCP server is what actually updates the DNS
server's database.
My Windows laptop for instance, may get different IP addresses using DHCP
depending on what physical location I connect it in. but it's always the
same DNS name.

I did this once a long time ago after googling for a quick fix, Not sure I
remember everything.
IIRC it was putting an empty hostname in /etc/rc.conf like: hostname=
and something like the following in /etc/dhclient.conf:
interface em0 {
send host-name workstation;
}
In Windows, the hostname would be the machine name, and since you know
it's always the same (as per above) sounds like you know the hostname.
Substitute for your interface and hostname.
The way this should work is your box does a force send hostname to the
DHCP server and the DHCP server should update the DNS server. At least if
the $MS boxen are setup correctly.
