This sounds like you recreated the 'example.com' zone again on another 
DNS server that is external to the Samba AD DC

It wouldn't resolve 'example.com' would it, you have just deleted all 
the zone records.

AD dns domain. Your DC's should be authoritative for the AD dns domain 
and forward anything unknown to an external DNS server.
