Hi,
I assume that adding your users to the power users group hasn't worked for you...If your users are installing ONLY msi packages (which you can create yourself if needs be) then you can tell the OS to always install msi's as admin by setting the
' Always install with elevated privileges'
policy in the gpo, which exists in both the user and the computer sections at -
Administrative Templates\Windows Components\Windows Installer.
If you are dealing with non msi installs, then you might find that applying the nt4 security format to your workstations works - search at
www.microsoft.com/technet
for "compatws.inf" for more info. Obviously both of these options severely lessen the secutity on your machine. In your shoesI'd make users come to your dept if they want anything installed, that way you retain control of what does or doesn't go on your desktops.
