Using new sites
Platí pro: Windows SBS 2003
You or users can add new sites to the SharePoint-based intranet at http://companyweb/. For example, the address of the new site would be http://companyweb/newsite/.
You can specify that these sites have the same permissions that are applied to the default site, or you can specify different permissions. All domain users with accounts based on Windows® Small Business Server user templates have access to the default site, but on the new site, you can restrict access to all but selected users. You must add these users to site groups by using Windows SharePoint Services administration tools.
By default, all domain users with accounts created by using the Add User Wizard or updated by using the Change User Permissions Wizard have access to the company's internal Web site.
