AD Password Control - Freeware

Password Control is a tool designed to allow helpdesk staff and other IT support personnel to reset user passwords.  It has a simple and intuitive interface that many users find more productive than a custom MMC console.  Password Control is designed to work with Active Directory based domains.  It also features other functions such as the ability to enable and disable user accounts (you can edit a config file to remove these features if required).
