Cant access Windows Share folder after upgrade from w7 to w10

Hello, I read a few info about it but i still haven't found a solution. I have been using LibreElec and the Pi for years without problem.

I used to have a windows 7 "server" to share movies across the house, playing on HTPC or Raspberry Pi.

Today I updated the server to Windows 10 and I now not able to find my share folder on my Pi.

My set up: Windows 10, with shared folders set to share with Everyone

Rapsberry pi 3 with Kodi 17.6, LibreElect 8.2.5.

I do in Kodi:

Add video

Browse

Add Network Location

SMB

Server Name: my PC name

Shared Folder: my video folder

Ok

ERROR Operation not permitted

It used to work with Win7.

I would like to avoid having to create a user and pass on my w10 machine.

How can I make it work?

Suggestion?

Thank you.

Thank you, I was trying to avoid using username and password but doing so it s working.

FYI, Server name has to respect upper and lower case. I didn't have to use the IP.
