You need to upgrade Samba, 4.2.x is just too old, but then Jessie is now
EOL and even if it wasn't, the libs etc that a supported version of
Samba needs will be to old, so upgrade everything.

That is the default server services line, so you don't need it.

That is not how you turn off netbios on a DC, you need:
server services = -nbt

Why do need ntlm auth ?

Oh dear, by setting 'vfs objects' like that, you have turned off the
defaults 'dfs_samba4 acl_xattr'. If you are going to set 'vfs objects'
on a DC, you need to set them like this:
vfs objects = dfs_samba4 acl_xattr full_audit
