Hi,

I've got a setup with the same purpose, serving machines with a mix of 
operating systems, Windows NT4, 2k, 7 and 10. The same machine data is 
used by all the machines in the group. The machine group is on an 
isolated VLAN, and there's only permitted incoming traffic from another 
VLAN for updating data files on the local server. There are 2 users with 
read permission and 4 users with write permission to the only share.

I chose another approach with a standalone server. There's really no 
need to use a domain for a few machines, which complicates things 
unnecessarily. My setup is using Archlinux, and I keep it reasonably 
fresh, currently at Samba 4.23.5. I started out with Debian when I set 
it up 3 years ago, but I never got it to work. The current setup has 
been working for 3 years without any problems. If you are interested, I 
can publish a more detailed description about the setup.

Best regards,

Peter
