Just a quick thought, I had a similar problem on my LAN. I set up /etc/hosts
files, and that did the trick for me. I could then dig both the fqdn and the
host name just fine. For example, for a machine on my internal lan with the
fqdn of empathy.whatever.net, I set up on the machines that had to reach it:
192.168.0.10 empathy empathy
In the /etc/hosts file. Man hosts for more info. :)
