I'm unable to remote-desktop into a Windows 8 machine from a Windows 7 desktop.
I am able to remote into the target Win8 box from another Win8 box.
I've checked the firewall permissions on both boxes as well as the remote desktop permissions. The machines are visible to each other on the local network. The error message indicates that "Remote Desktop cannot connect to the remote computer..."
I've created a local account on the Windows 8 box, as opposed to the Microsoft account I normally use, to no avail.
