I guess explaining my problem was the key to finding the solution.
I logged on Windows 10 with the local account and it tells me my password needed to be changed. I replaced it with the same one and now it's working again 
NB: For the share to be accessible you need to "Turn off Password Protected Sharing" in "Advanced sharing settings".
Hello,
My LibreElec on a PI3 was accessing my media directly on my Windows 10 (Creator Update). I've struggled a bit to make it work as SMB1 was disabled:
- On Kodi I added the share manually (smb://192.168.0.18:445 with a user / password)
- On Windows 10 I created a local account and shared my folders for this account
It was quite painful but it finally worked.
It's been working for weeks now but since yesterday it doesn't work anymore. I don't remember changing something at all. I've tried a lot of different things but it just doesn't work anymore 
. Even reenabling Samba1 in Windows 10 (yes you can) had no effect at all.
Any help on the subject would be greatly appreciated!
