Thanks you for the pointer. I hope I read this correctly (It is kind of overwhelming), and unfortunately, that does not appear to be it.
1 - Unlike the mentioned description, access to network share works fine either way (Example command that works either way "powershell -command get-childitem \\server\share") - I have enabled CredSSP and I this might be why.
2 - Using passwd -R to register the password did not make the problem go away (In the windows tradition I restarted the service and killed all sessions)

Greetings, Blando, Frank (Helion Managed Engineering)!

Please read the documentation. It is explicitly explained there in great detail.
