While Windows 2000 Server install IIS by default on a clean installation, Window s 2000 Professional only installs IIS (now called Internet Information Services in Professional as well) if Peer Web Services was previously installed on the machine (meaning an upgrade from 95, 98 or NT running PWS). However, if it was not installed by default, you can add it by using the Windows Components Wizard via Add/Remove Programs in Control Panel (incidentally, this is now where all Windows components are added, different from NT 4). Of course, you will need TCP/IP installed on the system prior to installing IIS. The tool to manage IIS is still called Internet Services Management (ISM), and is still an MMC snap-in. Installing IIS will create a directory called Inetpub, under which you will find the associated storage directories for the given services.Examples of the services installed include a default Website (wwwroot), default FTP site (ftproot), and virtual SMTP server (mailroot). Components can be included or excluded as you see fit. You can also control the properties of each and create new virtual sites as you would in IIS. To control Master properties, or those that will be inherited by all sites, go to the properties of the computername in ISM, and choose to edit a service (like WWW Service).
