Came here and fixed the "profile cannot login" problem. Changed the .bak to the main and the main to the .bak etc... Once I did that it solved the problem for a while but when I started my computer this morning had the same problem. Fixed it again and did a system restore. Now when I login the wireless Internet won't go past local only connection. Firefox won't open. Control panel doesn't load if I go to the new view versus the classic view. I created a new account as an admin but it tells me access is denied when I try to connect to the wireless network. On top of that firefox still doesn't work. Also i cannot log off or shut down. I have to hard boot it to start over. Basically same problems as the other profile. Anyone know what should I do to fix it?
