With XP Pro you can password protect any directory you want. Just rightclick the file or folder you want to secure and choose properties. Choose tab 'Security' and there you can specify what rights a user has to that folder/file.
that's a solution, however NTFS access permissions will not password protect any file/directory... it will set who can read/write files and folders, if one is not allowed then he'll get an *access denied* message, he will not be prompted to give any password.
but tell us... what you keep in protected dirs? eheh
