If you are using 127.0.1.1 in etc/hosts on Ubuntu, then you are using 
dnsmasq.
If you are using dnsmasq, then it is unlikely your dns setup will find 
the DC
Just a thought, is there a DNS server running on the AD DC ?
There should be and your client should be using this as its DNS server, 
AD lives and dies on DNS.
There shouldn't be a dns server running on your domain member, it should 
be using the AD dns server.
