<#

.Synopsis

   Determines which scheduled tasks (if any) have failed in the last 30 minutes 

   and sends an email listing those failures.

.DESCRIPTION

   Determines which scheduled tasks (if any) have failed in the last 30 minutes 

   and sends an email listing those failures.

.USAGE

    Create a scheduled task that has three triggers.  

    The triggers are on Task Scheduler log events 101, 103, and 202.

    Be sure that the scheduled task is running under an account with 

    enough credentials to read the log and to run this script, and 

    is running whether or not that account is logged on.

    Obviously, this script should be the action taken on trigger (program is

    powershell.exe, this script path\filename as parameter)

    Adjust the variables that begin with "$Email" below to be correct for your

    environment.
