Research that and the cause and cure is eluding MSFT.
When user inputs credentials and hits enter it goes to windows log in screen but when it should go to desktop the user just gets a black screen with movable courser. This has happened to about 4-5 different pc's so far. My current fix is to backup their files on the network, delete their local user account and have them log in as if it was the first time again which creates a new profile and they can then log in with no problems. I saw a thread on this here already but it was about 2 years old and didnt give me any information on what is causing the problem. My question is if there is a fix out for this yet or if anyone has identified the problem yet?
