This is a client setting and caused by SMB2 client redirector caching.
For details, see:
https://docs.microsoft.com/en-us/previous-versions/windows/it-pro/windows-7/ff686200(v=ws.10)

Set all three registry keys mentioned in the MS doc to "0" and reboot.

I'm sure there is a GPO for this as well.

Regards,
Marc


PS: The reason because this did not happen on servers running on Samba 3
was that SMB2 was not enabled by default before Samba 4.x.
