IE Hardening

[prathapml]

The updated ref.chm in XP SP2's deploy.cab references this:

[Components]section

IEHardenAdmin: Applies the Enhanced Security Configuration to members of the Administrators and Power Users groups.

IEHardenUser: Applies the Enhanced Security Configuration to members of the Restricted Users and Guests groups.

Is it valid for XP, or is it only meant for WS2k3?

I know after trying to get it to work, that the below works:

[IEHardening]
LocalIntranetSites=
TrustedSites=

But what is the status of IE Hardening, does it work? And if so, is it in the same way as it does on Svr2k3's IE6?
