The Password Expiration Notifier periodically checks all users in the specified Active Directory domain or OU to detect ones whose passwords are about to expire in a specified number of days, and then sends customizable notification e-mails to the account owners. The tool also sends summary reports to system administrators by e-mail. Armed with this tool, administrators can proactively resolve password expiration issues for end-users and service accounts. The Password Expiration Notifier also includes the "Plan and Test" feature which allows you to verify your configuration and see how many users will be affected by planned password policy changes without disturbing the users and changing AD settings.
