I've had a WHS box running without issue for a couple years. I turned on my computer today and got a balloon telling me that my Windows password did not match my WHS password; odd as I had not changed either. I've tried changing both to new passwords but WHS won't let me log into my personal account. I can get into the control panel to change passwords and view system status but access to files seems to be broken. Any ideas as to what would cause this?
