Windows 10: No permssion to access from one computer to the other (Solved)

Windows 10 Home, Version 103, OS Build 17134.1, WiFi Network works for Internet.

I cannot access either computer from the other with the removal of Home Groups. I have spent three hours reading help files, tutorials, etc, and have come up with nothing that will eliminate error messages such as "Windows cannot access \\John-PC\Documents", and telling me that I don't have permission to do that, and that I should talk to network administrator about the problem. I have been talking to myself to no avail.

I have changed a number of settings during the time spent trying to fix this, and no longer get pop-ups about such things as the network password, but, again, no solution. Many of the help files only refer to Home Groups, so are of no assistance; others have what look to be helpful information, but either I already have the suggested settings or just done give me the needed permissions.
