I am looking for additional reasons why our user is sometimes able to log in to his Windows 7 computer that is joined to the domain and sometimes receives the message "Username or Password is Incorrect"; and he says he is tryping in the correct password.
I have verfied the basics:
1. Proper case is being typed by the user
2. Correct user name is being type by the user
3. Computer can reach the AD server (Windows 2008
4. No log on to restrictions is set for this user
Thank you in advance.
