Same thing after automatic update to Samba 4.3.8 at Lubuntu 14.04 LTS 15.10 & 16.04 LTS. Can't access Win 7/8.1/10 shared unpassworded folders & printers.
But there is a temporary workaround which works for me on 15.10 & 16.04 (haven't try on 14.04 LTS).
In smb.conf [global] section put following lines:

   client use spnego = no
   client ntlmv2 auth = no
   client ipc max protocol = NT1

Now, when I'm asked for password, just enter my root password & select option "Remeber forever".
Same procedure for configuring Windows shared printers.

I hope this will help.
