Copy without losing file permissions

I have an NT domain controller, and I am going to replace it with a windows 2000 domain controller. The NT domain controller has user files on it. Is there an easy way to copy these files off to another server without losing the permissions? For some reason most of the user’s folders give them full control, but Administrators have only “special access”, so I can’t even copy it to another location.

Any suggestions would be greatly appreciated. 🙂
