As far as 1 is concerned, not really sure, but as far as 2 is concerned, 
well the answer is probably no, you really need SMBv1 for WINS and smbv1 
is now turned off by default everywhere. You will probably be better 
using Avahi for Linux and wsdd for Windows.

Thank you Rowland!

That's really the question -- I DON'T need smb1. So in that case do I
just
disable all the Wins and Browse List stuff? Do I even need nmb at that point? 
(or will it help with the Avahi and wsdd resolution?)

Basically, I have a network with 4 Linux boxes providing samba shares and then 
a dozen or so Win10 boxes and iPhones (accessing smb shares via the Files app) 
and the 192.168.6.14 (the wins server) also provides DNS via bind and ISC 
dhcpd with dynamic updates to DNS -- so name resolution isn't an issue.

I could just experiment turning wins off and see what connectivity/access is 
like. Is there an updated doc on setting up standalone without smb1 somewhere?

The crux of the matter is I'm not an Avahi or wsdd expert. When smb1 was 
enabled, there was clear documentation for configuring smb.conf to handle wins 
server, wins client, browse-master and election rules. It seems like since 
smb1 was disabled, there isn't any documentation about what that meant for 
existing configurations that had used wins, etc..

So if the answer is -- you can just comment out all the wins and domain master 
settings, I'm good with that, I've just never been fond of guessing.
