What are you specifying as the Share name?I am unable to get this to work when I update the smb.conf-opkg with my own workgroup name (and change it to smb.conf). I get a Microsoft log on screen.
I have tried removing the # from guest account = root and guest ok = yes but no go.
(On Windows 10)
Did you restart the Samba server (Services menu) after updating the smb.conf file
If you specify \\humax (or your humaxes name/ip address) and then browse does it show a list of available shares? (My Video, My Music etc)
