If you are going to run a Samba AD, then you are going to be running a
dns server 😁
When you do set up AD clients, they will need to use the Samba AD DC as
their dns server. Also, you might want to check the port usage, AD uses
a lot more ports.

You just need to remove the smb.conf and then provision again.

It is something built into AD, try reading this:

Oh it works, it actually works better than wins in my opinion.
