PowerShell script that checks to see if the password is expiring soon and notifies the user by displaying a window.

Check-Password.ps1

SYNOPSIS

Check AD user's password expiration status and prompt the user to change if needed.

SYNTAX

Check-Password.ps1 [[-DaysToStart] <Int32>] [[-DaysToMaximizeWindow] <Int32>] [-LockScreenOnPasswordChange]
 [<CommonParameters>]

DESCRIPTION

Displays a notification window for the user indicating that their password is about to or is expired, if within the defined parameters. It calculates the days remaining by using the date password was last set with the domain password policy's MaxPasswordAge. The window notification gives instructions to user on how to change their password and gives them the choice to wait for the password change and make the window go away. On the last day remaining the choice to postpone will be removed, forcing the user to change the password to remove the window. The window will disappear automatically if it detects the user has changed their password.

EXAMPLES

Check-Password -DaysToStart 4 -DaysToMaximizeWindow 2

Description: The window will not pop up until password expiration is less than or equal to 4 days remaining. The window will not maximize to Fullscreen until less than or equal to 2 days remaining.

EXAMPLE 3
