<#
.SYNOPSIS
    This function locates the computer that processed a failed user logon attempt which caused a user account to become locked out.

.DESCRIPTION
    This function will locate the computer that processed a failed user logon attempt which caused the user account to become locked out.
    The locked out location is found by querying the PDC Emulator for locked out events (4740).
    The function will display the BadPasswordTime attribute on all of the domain controllers to add in further troubleshooting.

.EXAMPLE
    PS C:\>Get-LockedOutLocation -Identity Jimmy.John


    This example will find the locked out location for Jimmy John.
.NOTE
-This function is only compatible with an environment where the domain controller with the PDC Emulator role is running Windows Server 2008 SP2 and higher.
-The script is dependent on the ActiveDirectory PowerShell module, which requires the AD Web services to be running on at least one domain controller.
