Something is fishy here. At some point you must put a login name and password (otherwise anyone could log in, right?
). I suspect your IP address has changed. Unless you have assigned a "Static" IP address this usually changes if a router (or phone Wi-Fi hotspot) is turned off or reset. Here's what I would try: DELETE the login that you have been attempting to use. Rescan and start over. At some point a user and password must be entered to access your PC (assuming this has been set up on your Win 8 PC - maybe this is the problem? Have you set up a "Standard" User and/or Administrator?). You are getting the "account has no permissions" for a reason. Wrong user name and/or password will cause this.
Have you set up your PC with a "Standard" user? Or do you log in with Administrator access? Win 8 isn't much different than Win 7. I've had little problem accessing my Win 8 PC's. I have mine set up with "Standard" users to add a level of security. Only I am an Administrator and can fiddle with the system. Most agree this is a good practice. If you haven't done this I would study this and suggest using only Standard users for general access to your PC, and set up an Administrator for installing apps and fiddling with settings. Be careful if you change this because it can mess up your desktop. This is one of the Win 8 changes that takes getting used to, but is generally thought of as a security improvement.
Sorry. I'm at a loss as to what else to try.
