Use PDC passwords for Win2000 pro

WE are adding some Windows 2000 pro machines to our NT network and I would like to know if we can get the Win 2000 machines to use the PDC to validate user credentials like a Windows 95-98 machine. Now we have to set up a local account on the Win 2000 machine that matches the users Network credentials. We set the users up as restricted access, we the add mine and my associates credentials (as Administrators) to each machine. Is there a better way to set these up. Now if any of these password are changed we would have to change them on all the Windows 2000 machines.
