If Samba set as is the DNS server for the network, then this kind of
thing can happen.

What you should do is have a different BIND 9 server be the DNS server,
with a zone of type 'forward'
for the Samba AD zone, pointing at the set of AD DCs.  

This means that this better-suited DNS server, for which tuning guides
and performance documentation is available can handle the main internet
access load, and Samba just does the Samba stuff.
