Somewhere along the line, the shared folders stopped showing up on either laptop. When I first set up the sharing, I could see the shared drives and folders in File Explorer under Network. Both computers show as connected to the same network. I have additionally mapped three of the folders as drives on the second computer which I will call backup. I have turned file sharing on for everyone on both of these drives, as well as sharing also turned on on a number of folders on these drives. One laptop, which I will call main, has two external USB 3.0 hard drives. I am using the current version of Windows 10 home. I have two HP laptops connected via an Ethernet switch.
