Install the ADMINPAK.MSI file from either the Win2K Server CD, or extract it from the service pack that you are currently using (preferrably from the same service pack revision that is active on both systems). That will give you all of your AD and server-services admin tools. You can also administer shares on any of your NT-based systems by right clicking on "My Computer", and selecting "Manage". From there, right click on "Local Computer" and select "Connect to another computer". Then, just select the machine you want to manage by using the browser pane, or entering the machine name/IP into the address bar.
