[Samba] Windows Server 2019 / Windows 10 LTSC can't access samba shares on Debian stable 4.5.12

[Thomas Glanzmann]

Hello,
my smb.conf is:

[global]
        workgroup = DIRECTORY
        interfaces = 10.10.10.1
        security = user
        map to guest = Bad User
        rndc command = /bin/true

[iso]
        comment = ISO
        browseable = No
        public = Yes
        guest only = Yes
        writable = No
        directory = /export/ISO

I'm using Debian 9.5 with samba version 4.5.12+dfsg-2+deb9u3. I can access the
share find with windows xp - windows server 2016. However with Windows Server
2019 and Windows 10 LTSC I can't access it. Any idea what I have to change? I
already tried to use samba-4.9.1 with the following configuration:

[global]
        workgroup = DIRECTORY
        interfaces = 10.10.10.1
        security = user
        map to guest = Bad User
        rndc command = /bin/true
        # server role = STANDALONE
        netbios name = filer

        cache directory = /local/samba-config/common/cache
        lock directory = /local/samba-config/common/lock
        log file = /local/samba-config/common/log/%m
        ntp signd socket directory = /local/samba-config/common/signd
        pid directory = /local/samba-config/common/pid
        private dir = /local/samba-config/common/private
        state directory = /local/samba-config/common/state

[iso]
        comment = ISO
        browseable = No
        public = Yes
        guest only = Yes
        writable = No
        directory = /export/ISO

Afterwards I started smbd and nmbd with the options '-c' and they did work for
me with the following error message:

[2018/10/11 12:30:58.556337,  0] ../source3/lib/interface.c:652(load_interfaces)
  WARNING: no network interfaces found

10.10.10.1 is configured on the interface lo:

1: lo: <LOOPBACK,UP,LOWER_UP> mtu 65536 qdisc noqueue state UNKNOWN group default qlen 1
    link/loopback 00:00:00:00:00:00 brd 00:00:00:00:00:00

       valid_lft forever preferred_lft forever
    inet6 ::1/128 scope host
       valid_lft forever preferred_lft forever

I want users without authentication to access shares. One is r/w, all
others are r/o.

Cheers,
