Yes, that should work. If it doesn't work for you, you need to tell us
some more details about your smb.conf and maybe provide a network
capture of the failing DNS update.

Fair enough. Again, we probably need a network capture to see what's
going on with the DNS MMC failing to update the SOA record.
