I have two desktops both have Windows 8 Pro 64bit, both just use the stock AV. Router is the Asus RT-N66U Both desktops have the same sharing settings (as far as I know) but I'm having problems accessing one of them with two different devices. Using my Patriot Box Office media player and the AiCloud software (from the router) I get a pop-up asking for a login and password and I can't get in. It fails every time. But that's just with one of the desktops, the other it never asks, just let's me in. I don't get it Any idea what to try to get this to work or any settings I need to mess around with? ...I don't have any problems accessing any of my shared folders using my Android devices either if that matters.
