I'm at work at the moment and can't check the actual filenames, but if
you go into /etc then type dhcp<tab> (I think it's /etc/dhcp, but
don't hold me to that), there's a conf file in there. One of the
options is "send name to server" or something very similar to that.
Sorry to be so vague, but uncommenting that line and putting in a name
to send, solved that problem for me. You'll have to restart the

sudo ifdown eth0 && sudo ifup eth0

(substitute eth0 for whatever your network interface is)

Could I be any more vague? :-) But hopefully that gives you the clue
that you need.
