IIS Manager is a graphical interface for configuring your application pools or your Web, FTP, SMTP, or NNTP sites. With IIS Manager, you can configure IIS security, performance, and reliability features. You can add or delete sites; start, stop, and pause sites; backup and restore server configurations; and create virtual directories for better content management, to name only a few of the administrative capabilities. In previous releases of IIS, this tool was called the Internet Service Manager.
