Thanks for the exhaustive answer/query. The "different machine" was in the same subnet. I did actually ping from it to make sure the DNS server is reachable. The DNS server is running myDNS.
I think the 'dig' actually tested the deamon, as I didn't touch the /etc/resolve.conf, and I have no nameserver setup. I managed to solve the problem by playing with the firewall configuration (using the GUI). I just had the check "eth0" under "trusted devices", and it worked.
