AD account lockouts

I'm looking for a PowerShell script that would show the event viewer ID of 4740 and  'Additional Information' of 'Caller Computer Name'

I created a script that would automatically send me an email in event of any account is getting locked out, if you want I can post the script and instructions. I am not so good in PS so I can't create you the exact script you are looking for

See the PowerShell script in my article

this was very helpful

Also check out Microsoft's free tool called Account Lockout and Management Tools.
