If you just want Administrative tools for the local machine
you should already have them. Go to Settings|Control Panel
and the Administrative Tools icon should be there. Also, if
you would like the tools to be visible from your start
menu, right click on the Start button, click Properties,
then in the Taskbar tab search for the checkbox that says
"Show Administrative Tools", or to that effect. If you wish
to add Domain Administrative tools in order to manage
Windows 2000 server you will need the adminpak.msi file
from the original W2K server CD. Hope this helps.
