Locking down the User Interface

[RWI Guest <gh068 ghit co uk>]

Hello,

Is there anyway that you can lock down the user interface to prevent
users from changing the backdrop, colour scheme, font size, screensaver
etc, so that all desktops have the same look and feel. Is there any
tools to achieve this, or is it a case that admin permissions must be
set on all tools and the users GUI profile?

Thanks in advance,

David Sharples.
