SMB not working on MXQ Pro + 4k

Hello i installed CoreELEC-Amlogic.arm-9.0.1-Generic two weeks ago. I would like to use the embeded Samba Server, but it do not show up in my network.

Also tried this Kodi Box as client on my Windows SMB Server but get every time " SMB invalid argument". On other Kodi Setups (Android Tablet/Phone) this works great. So there must be a problem with this Armlogic installation.

Hope somebody can helpp me

kind regards
