Trouble is that smb v1 is horribly insecure. Even Microsoft tells
people not to use it.

I'd think the feds would have figured out that smb v1 is a bad
protocol to use and outlawed it.

At home, while I do not have win10 talking directly to samba on my
LInux desktop, I also have a Synology Disk Station and have configured
it to use only smb v3, and in the mount command on Linux I specify
smb v3, and it works fine.
'course, that's the samba client, not the server. I haven't really
investigated why I can't directly access win10 from linux and vice-
versa, so it may be a v1 vs v3 issue. However, at work I had no trouble
accessing my home filesystem on linux from win10. haven't, so far,
figured out what the difference is.
