I have a customer with a peer to peer network. They have just added a Windows 10 Home computer to the network. The new computer shared folders can be accessed by any of the other computers on the network. Additionally the new computer can access shared folders on a Windows 7 computer but is not able to access shares on another Windows 8 computer. The Windows 8 computer can access shared folders on the new Windows 10 computer.

Network discovery and file sharing are turned on on all computers. Password protected sharing is turned off. When attempting to see the shared folders on the Window 8 machine from the new Windows 10 machine a prompt asking for a Username and password appears. I enter the logged in username from the Window 8 machine and the password that user enters to log on to the Windows 8 machine.

Each time it tells me the username or password is incorrect. The shared folders are set for full access by Everyone. The shared folders on the Windows 8 machine are easily accessed from the other two computers on the network. I can successfully ping the Windows 8 machine from the new Windows 10 machine.

Does anyone have any suggestions regarding what might be causing this and how to fix it?
