OK, you are running 'samba_dnsupdate', so this means a DC (if it isn't,
why are you running the command ?), which means you cannot run dnsmasq
on it. Point the nameserver to its own ipaddress and remove dnsmasq.
It sounds like you are possibly running a strange (to AD) dns setup, the
DC(s) must be authoritative for the AD domain and all domain computers
must use the DC(s) as their nameservers and anything outside the AD
domain will be forwarded to external dns servers by the DC(s).
