Install MS IIS (internet information server) as your web server. It is included with W2K (though probably not installed on your machine yet by default)
The following information is from W2K help files. I searched for "install iis"

IIS installation
Note
Information in this topic refers to IIS version 5.0; for information on later versions of IIS, check the documentation that accompanies the installation program.
Internet Information Services 5.0 is not installed on Windows 2000 Professional by default. You can install IIS or select additional components by using the Add/Remove Programs application in Control Panel.
To install Internet Information Services
Click Start, point to Settings, click Control Panel and start the Add/Remove Programs application.
Select Add/Remove Windows Components and then follow the on-screen instructions to install, remove, or add components to IIS.
Note
If you upgraded to Windows 2000, IIS 5.0 will be installed by default only if PWS was installed on your previous version of Windows.

IIS software checklist
Internet Information Services requires that the following software be installed on the computer prior to installation:
The Windows TCP/IP Protocol and Connectivity Utilities.
The following optional components are recommended:
The Domain Name System (DNS) service installed on a computer in your intranet. If your intranet is small, you can use Hosts or Lmhosts files on all computers in your network. This step is optional, but it does allow users to use "friendly" text names instead of IP addresses. On the Internet, Web sites usually use the Domain Name System. If you register a domain name for your site, users can type your site's domain name in a browser to contact your site.
For security purposes, Microsoft recommends that all drives used with IIS be formatted with NTFS.
