Windows 10: Win 10 computer cannot access Win 7 computer

This was working for a while, but no longer is (as typical). I did have to reinstall the OS on the Win 10 computer, nothing changed on the Win 7 computer. The Win 7 computer shows up on the network, but if I click on it says "unable to access". Discovery in the options is turned on, and the C drive on the Win 7 is set for sharing with all permissions checked.

Win 7 and Win 10 on network

I have home network with separate modem, router, and WAP's. My Windows 7 computer does NOT list the Windows 10 computers on network computer list but the Windows 10 computers network list DO list the Windows 7 computer.

Turned off firewalls, gave permissions, shared drives. Nothing allows Win 7 computer to access the Win 10 computers.

Any suggestions for a fix?

 

File Sharing between homegroup computers using Win 10 and Win 7

None of he suggestions offered have solved he problem. However, I found out why I was not able to see the Window 7 PC folders on my Win 10 laptop. It was all related to the difference in how you find a computers on a homegroup. As it turns out, the
Windows 10 menu structure for getting to the Network is different between the Win 7 and Win 10 operating systems. The homegroup computers can be seen on the Win 7 buy going to Network and File Sharing on the Control Panel and by clicking on the the House
Icon between the Win 7 PC icon and the Internet Icon. These icons are not part of the Network and File Sharing menu on Win 10. Instead, the homegroup computers can be found on the Network icon under the Computer Menu on Win 10 computers. Once I found Win
7 listed under the Network Icon on the Win 10 computer I was able to access all of the shared folders on the Win 7 PC.

 

Win 10 computer unable to access shared files on Win 7 computer

AH HA, Problem Solved: The problem is in Norton's "Smart Firewall" -- I turned this off and I can now access the shared files.. For some reason, Norton started treating the Win 7 connection to my home network as "public". I listed
my Win 10 computer as a "trusted source" and everything is back to normal.
