Microsoft has released an important security update for Internet Explorer 5 or later on Windows XP and Server 2003 machines.  This update closes a critical vulnerability that can allow unauthorized access to your computer.  Those that have Windows Automatic Update turned on (default/recommended) need do nothing; you will receive this update automatically.  If you believe you may not have Automatic Update turned on - even if you do not use Internet Explorer as your default web browser - please follow the instructions below.
