Holy crap I got it to work. smbv1 is not enabled by default on Linux.
Once I went through the tutorial and added
client min protocol = NT1 server min protocol = NT1
to smb.conf, it worked and I could connect!
Sadly it still wouldn’t accept my username and password, but I set it to allow anon login and that’s working 100% right now. So… just need to figure out why it won’t accept username and password. Moment of truth comes when I test VLC again too.
