For some reason I am no longer able to access my PC via unattended access. It was working fine and then over the last week it showed this computer offline at all times. I removed the computer from the admin control center and attempted to add it back, but it doesn't stay on the list. I've tried restarting the tech console and no matter what I do unattended access does not work on this machine. I have no problems on my other computers. This unit is a windows 8 machine, but I do have a couple of other 8's that are working fine. Any idea how to address this?
