I made a USB flash of ver 3.0.766 and is now running 3.0.773.
I realized I was not able to "see" my boxes in windows anymore, and try to locate why.
Tried to remove the SAMBA service, and activated the service again, but I still cannot see the boxes in Windows.
However the netinterface is working in Chrome entering the IP of the box.
I attach the SAMBA log, and see some faults which I dont understand.
