Copying NT WS Profiles

I have about 20 NT 4.0 workstations that we use for community PC’s with multiple users logging onto them. These PC’s need to be replaced due to lease expiration. How can I copy the profiles off of these PC’s and put them on the new PC’s without having to have the users relogin and reconfigure their profiles (IE: mapped drives, desktop apperance, ect.) We do not use scripts at all. All settings on done on an individual basis. I know just copying the profiles over does not work.
Thanks in advandce.
