How to setup default permissions on NTFS partition?

Hi,
I recently installed Windows 2000. Initially my C drive was formatted as Fat32 (the Windows 2k system partition). Later I used Convert to convert it to NTFS. When I checked the permissions on the folders, Everyone has all the rights.
I want winnt folder be controlled by Administrator. And each user has their own user folder. But I don't know what default permissions I need to assign to EveryOne?
I am just wondering whether there is any tool to automatically assign permissions to the folders?

Thanks
