Windows cannot access \\computer_name

Question

if I type \\cori\f in File Explorer in the top bar, disk F on the computer named "CORI" opens nicely
but if I only type \\cori, the error message appears "Windows cannot access \\cori You do not have permission to access \\cori Contact your network ..."
I mention that I have 5 computers with Windows 10 pro 64 in the network, everything works fine. I tried everything I could find on the net, so any suggestions are welcome.
Thank you

Answer 1

Ok you can try to:

• check the workgroup
• Make sure "Turn on network discovery" is selected
• Check you are logged in with an account that has the necessary permissions to access shared resources on the "CORI" computer.
• Try accessing the computer using its IP address instead of the hostname. For example, try \\192.168.x.x instead of \\cori. This can help identify if the issue is related to name resolution
• Ensure that the firewall on the "CORI" computer is not blocking the incoming requests

Answer 2

as I mentioned, I can access any disk on CORI,
i can access any shared resources on the "CORI" computer less the shared printer.
 so it's not a firewall problem
network discovery is on
it doesn't work with \\192.168.x.x either, the problem is completely different
