I wrote this PowerShell script last year when I wanted to automate the report of Active Directory user objects with Windows PowerShell. It was written with the intention of reporting the user objects within specific organizational units (OU) in two AD domains.

Be notified by email when an Active Directory user account is locked out, this PowerShell script will grab the most recent lockout event and send you an email notification. Requires a Windows 2008+ domain controller and an email system accepting a relay from the DC.
