Hi, I having problems with a Vista Home Premium laptop, everytime I log on an error appears "Windows could not connect to the User Profile Service service. This problem prevents limited users from logging on to the system." I have checked the accounts and this is an administrator account. I also noticed that laptop harddisk runs for a while. I scanned the laptop with AnitVir and spyware program, but nothing was found. If you can give me a solution I would be grateful.
