Windows 2000 Server Help - FTP

Hey,

I have a question about the Windwos 2000 server. I am leasing a dedicated server running IIS 5.0 and what I am having trouble learning is how to set a user folder for FTP. In otherwords, I have a path set for the web site. Now under this folder, I want to have several more folders where each folder is for each user. I can add a user to the NT user list in the server. Then I go to the FTP properties and can include that user for the ftp service. But where do I set what folder that user is limited to? I have looked everywhere and cannot figure this out.

Any help would be appreciated!
