<# Author: Matt Schmitt Date: 12/4/12 Version: 2.0 From: USA Email: ithink2020@gmail.com Website: http://about.me/schmittmatt Twitter: @MatthewASchmitt Description A tool checking for Locked Accounts in AD, checking if a user is locked out, unlocking the user's account and for resetting a user's password. UPDATED 12/11/12 Added some Error Handling Check if server is available. If not, skip sever and do not try to exicute code on it. Changed the way I handled the $servers array. This is so I can remove a server if it is unavailable. Check if supplied user is in AD. If not, Ask the admin to re-enter username Added Comment blocks for each section. UPDATED 12/10/12 Added the use of functions to clean up repeated code. Cleaned up Password reset code to use a foreach that looks at the $servers array. Added some needed Comments UPDATED 12/4/12 Cleaned up Checking LockedOut Status code - replaced with foreach statement that looks at $Servers array Cleaned up Unlock code - replaced with foreach statement that looks at $Servers array Cleaned up Get pwdlastset date - rewrote to use the method I was using for other lookups for AD properties. #> #Imports Active Directory Module Import-Module -ModuleInfo ActiveDirectory Write-Host -object "" Write-Host -object "PowerShell AD Password Tool" Write-Host -object "" Write-Host -object "This tool displays the Exparation Date of a user's Password and thier Lockedout" Write-Host -object "Status.
