Windows 7 login denied

Make sure that the account is not disbaled or expired. Does this happen with any other machine? Make sure that the password is not expired either. Make sure that the username and password are correct.

Will.

Is this computer on a Domain or Stand Alone?

If Domain, log in as domain admin and make a new account.

If not on domain, it is a password error?  or other error?

Check if her ID is in denied list of the "Deny logon locally" user right GP. User ID should be enabled.

Aside from above recommendations also check keyboard language on login screen and is numlock on or off. :)
Many times if different input methods are present for some reason can be wrong keyboard type. or on laptops numlock is on (on keyboard without numeric keypad then some letters and symbols become numbers), or on regular keyboard numlock is off and user tries to type number on numeric keypad.

The computer is in a domain environment; her account is in good standing, and she is able to logon to another computer. I have also tried to logon to the computer remotely with both the local admin account and my own account  but got the same error.

Can someone log in locally with either a different user name or as admin (but local not remote)?

You may need to try a Windows 7 Startup Repair, but I am not sure if that will correct the problem.

Check if the computer user group contain "NTAUTHORITY\Authenticated Users" user.

If it does not then no one can login to the computer except authenticated user.


Please check below link. It has info how to remove users to logon on computer.
