And for those that didn't get the smb.conf

     workgroup = SAMBA
     security = user

     passdb backend = tdbsam

     printing = cups
     printcap name = cups
     load printers = yes
     cups options = raw

     comment = Home Directories
     valid users = %S, %D%w%S
     browseable = No
     read only = No
     inherit acls = Yes

     comment = All Printers
     path = /var/tmp
     printable = Yes
     create mask = 0600
     browseable = No

     comment = Printer Drivers
     path = /var/lib/samba/drivers
     write list = @printadmin root
     force group = @printadmin
     create mask = 0664
     directory mask = 0775

You are running Samba as a standalone server.

I think your problem is that on 3.6, it was 'ntlm auth = yes', this 
changed to 'ntlm auth = no' at 4.7.0 and then again to 'ntlm auth = 
ntlmv2-only' at 4.7.0

To test this, add 'ntlm auth = yes' to your smb.conf, if this works, I 
would find out how to turn off SMBv1 on your Windows server.
