NT 4 polices on W2k Workstations

I have a NT 4.0 Network (Server) with Win95/98 workstations. We use policy editor to control the desktop of our users. We have just added W2k workstations. How do I get control of the W2K workstation desktops (ie. hiding the My Network Places icons, disabling the mouse right-click button, etc.) using the policies that I already have in place?

I hope this is clear, if not please let me know what other information I need to provide.

Thanks in advance.
