[Samba] System Policy Editor not running on XP

[Steve A]

This Samba Wiki entry:
http://wiki.samba.org/index.php/Implementing_System_Policies_with_Samba

... says how to use the MS System Policy Editor, and implies it runs on XP. 
When I run "adminpak.msi" (extracted from Windows 2000 SP4) it says it wil l 
not run on this version of Windows, and if you continue to install you get a 
System File Protection error.

Is this just the way things are now, or have I missed something?

If it's the way things are, how does one apply system policies?

Thanks,
Steve :)
