You receive a message that states that the account has expired and you cannot change your password when you unlock a computer that is running Windows Vista

When you unlock a computer that is running Windows Vista, you receive a message that states that the account has expired and the logon process cannot continue.

This issue occurs after a domain administrator resets your password and configures your account to require that you change your password the next time that you log on. However, you are not given the option to change your password.

To work around this issue, click Switch User, and then log on.
