Can't access NAS from Rpi2

@DavidUcles

with the W7 file server I can see the shared file directories but I can’t see the videos inside them

Your W7 file server would reject SMB1 request so you are a bit between a rock and a hard place here.
What is the Max Protocol that you have configured in Kodi now?
But first you have not followed what I suggested!

@fzinken

nano .kodi/.smb/user.conf
And add only this lines nothing else
