Don't believe Ubuntu :-D

Is this on the DC ? if so, can I suggest 'apt-get purge network-manager'

This will remove Network Manager (you don't need it on a machine with a 
fixed IP)
If resolvconf is installed, I would also remove this.

Set /etc/resolv.conf to point to itself:

search smbdomain.com
nameserver 127.0.0.1 # or you could use the DCs IP

Remove the 'dns' lines they do not really belong in this file.

See if this fixes your problem, if not report back.
