A server prompts Ann, a user, to reset her logon password. The next time Ann tries to log onto the server, she cannot remember her new password. After several failed attempts, Ann receives a message…

Because Ann forgot her new password, the administrator must reset it to a known temporary value so she can authenticate; without a password reset, Ann cannot log in even after the lockout is cleared.

Multiple failed login attempts trigger the account lockout policy, which sets a flag that blocks further authentication attempts; the administrator must explicitly unlock the account in the directory service to allow logon again.

Rebooting the server does not clear account lockout flags or change stored credentials - those are persisted in the directory service and survive restarts.

Recreating Ann's profile addresses profile corruption or data issues and has no effect on authentication failures caused by a forgotten password and account lockout.

Checking Ann's profile examines profile settings or stored data, which is unrelated to resolving an authentication failure caused by a lockout and forgotten password.

Verifying Ann's ACL relates to her permissions on specific resources, not to the account lockout or credential reset required to restore her ability to log on.
