[Samba] some questions to samba and W7 and W10

[Achim Klausmann]

Hello,

i got some clients (WINDOWS7 and WINDOWS10) to connect to samba shares.

OS is openSUSE 12.2; 13.1; 42.1
Samba-Version: 3.6.7; 4.1.22; 4.2.4
smb.conf is shown below.

The samba setup is a workgroup setup, the W7-clients
are set up to the workgroup 'workgroup'.
No further changes are made to the W7-clients.

samba setup:
groupadd workgroup
chgrp -R workgroup /srv/samba
chmod -R 770 /srv/samba
chmod g+s /srv/samba
for ((i=1;i<21;i++));do useradd -g workgroup -p "" user$i;done
for ((i=1;i<21;i++));do pdbedit -c '[NX ]' -u user$i;done

Connecting W7 to the samba shares is working,
but W10 won't connect to the shares.
net use y: \\192.168.0.98\share1 /USER:user1
net use z: \\192.168.0.98\dump /USER:user1

This won't work on W10-clients.

First question:
Man pages:
client max protocol (G)
The value of the parameter (a string) is the highest protocol
level that will be supported by the client.

Are here meant WINDOWS-clients or to samba-clients?

Second question:
How can connect to the shares with 'net use' command?
Which options are realy necessary?

smb.conf:

[dump]

This setup is working since openSUSE 11.4 and WINDOWS XP.
