At first, thanks for your response, I appreciate it.
Ad my "reinstall approach": I tend to be rather defensive on a
productive DC like this one. So deleting samba-related files etc is
something I avoid ... -> I would need a definitive howto for this,
because I know too little about the details. I don't want to corrupt any
AD-related information etc
Maybe the change from the Louis-packages to the backports-packages
and/or 4.16 -> 4.17 left some wrong packages behind or so.
I still have 2 servers to upgrade there, so I am open to suggestions
(and thankful if they work ;-) ).

I'd be glad to be able to spot this. Posting my steps was a try to
actually find something.
Over the day pressure built up so I decided to do the mentioned
"reinstallation". That was simply one of my last ideas (and I wanted to
go for 4.17 as sooner or later that step will be necessary anyway).

I just mentioned it because it might have been related. "dig" works ok
on that machine ... I don't need the "host" command, it was just used in
some example command on the Samba Wiki or so.
thanks all, Stefan
