thank you. That works, but there is one thing, I don't understand. In
the past there was a nmbd and smbd process. It seems that now only nmbd
is running, and if someone is connecting, smbd is spanned. Is that
correct?

Thanks to the feedback I have received by you and Andrew, samba is now
running on an unused ethernet interface. Thank you. However I still
can't access the windows share from the new windows versions, but I now
tried it from the cmd prompt and got a good error message:

> C:\Users\Thomas>net use \\10.109.0.1\tmp
> System error 1272 has occurred.

The error code lead me to:

The following command resolved my issue:

Set-ItemProperty -Path "HKLM:\SYSTEM\CurrentControlSet\Services\LanmanWorkstation\Parameters" -Name "AllowInsecureGuestAuth" -Type DWord -Value 1

Afterwards it works. Also with the Debian Samba.

Cheers,
