Hi

I'm running Ubuntu 20.04.2 LTS

I can connect to a Windows server to display the shares, but I cant browse any of them. It says:
Unable to access locations: Failed to mount Windows share: Invalid argument.

From researching it, I've made lots of tweaks to /etc/samba/smb.conf - I've lost track of all the changes. I wish I made a backup of the original file so I could start again, but below is a paste of the exact contents right now.

Thanks for helping!
