Desktop policies wokking but not!!

Hi to all:

I seem to be having a problem with windows policy editors.

Using Win9x policies coming through a novell network / zenworks starter pack.
I am trying to disable all desktop screen savers / wallpaper “And use a uniform interface”. Using screen saver = scrolling / Wallpaper = windows default. I also have the don’t save setting at exit is checked.
The policies do download properly, but there are users who insist on using the webshots wallpaper / screen savers. They
seem to override the system policies. Is there anyway that I can disable the intrusion of webshots?

Thanks
