MORE INFORMATION
883256 How to manage Internet Explorer add-ons in Windows XP Service Pack 2

 
Please note that editing XPSP2 Group policy settings requires that you install the ADM Files for XPSP2 on your server, or edit from a XPSP2 Client machine on your domain.

Once these are installed (or indeed you are editing directly from a XPSP2 Machine), the location in Group Policy for the Add-on controls of Internet Explorer can be found in: Computer Configuration\Administrative Templates\Windows Components\Internet Explorer\Security Features\Add-on Management
