I have a small network with around 5 computers, but no server. So I setup a shared folder on one of these computers for the other computers to access. This normally works fine, but every now and then one or two computers cannot access the shared folder, giving the following error:
Windows cannot access <shared folder>
You do not have permission to access <shared folder> ...
At the same time, other computers can access this folder. As I write this question, two laptops connected over WiFi cannot connect, but the computers connected by cable can.
The computers that cannot connect can see the host computer and ping it successfully.
The host computer is running
Windows 8, the other computers are a mix between
Windows 8 and
When I ping the host computer it has a IPv6 address if this makes a difference.
