Welcome to the forum. Have you right clicked on the folder you want to share and created a share giving everyone rights? Then you connect via \\pcname\sharename
Welcome to Ten Forums @rothamar
Samuria is correct. The PC you are trying to connect to doesn't appear to have any shares available. You need to go to that PC and share a folder on it before you can map a drive to it from this PC.
Share Files and Folders Over a Network in Windows 10
On both systems, Control Panel, Programs and Features, Turn Windows features on or off.
Scroll down to SMB 1.0/CIFS File Sharing Support. Check Client and Server.
Click OK and let it update then restart.
See if that helps.
You have set the share to everyone but then you may need to set NTFS permissions on the folder some folders have special permission like anything in a users profile
