Samba 4.3.11 is EOL from Samba's point of view, can I suggest upgrading 
to 18.04 and using the Samba packages from here: http://apt.van-belle.nl/

And there is most likely your problem, you have broken your dns, the 
zones are stored in AD. Try reading this:

Why isn't 'server7' replying ?

Probably because of the incorrectly set up dns.
