I have a strange problem. My network is working, I can share the internet. But the host computer can't see the client computer. So I cannot share files. When I try to access a shared folder on the host computer from the client, it says I don't have permission, although I set all my computers to log in as administrators. Also, there are no computers listed under "Computers near me" folder.

This is most likely a permission problem, how do I set each computer to allow access to each other?

Thanks.
