		+
		+	This script can be used to restart a service via a scheduled task. The script will kill the process if the service does not stop within 60 seconds, and it will send an e-mail notification if the service does not start back up within 120 seconds and continue attempting starts every 120 seconds and sending additional notifications.

		+	This script allows you to recursively take ownership of a directory and all of its sub-files/sub-directories. This is sometimes necessary if you accidentally remove your own permissions from a directory and need to give yourself permissions again. You must be logged in as an administrator for this to work.
