How to Install IIS Prerequisites for Exchange Server 2003 on Windows Server 2003


Exchange 2003 Setup requires that the following components and services be installed and enabled on the server:

  • .NET Framework


  • Internet Information Services (IIS)

  • World Wide Web Publishing Service

  • Simple Mail Transfer Protocol (SMTP) service

  • Network News Transfer Protocol (NNTP) service

If you are installing Exchange 2003 on a server running Windows 2000, Exchange Setup installs and enables the Microsoft .NET Framework and ASP.NET automatically. You must install the World Wide Web Publishing Service, the SMTP service, and the NNTP service manually before running Exchange Server 2003 Installation Wizard.

If you are installing Exchange 2003 in a native Windows Server 2003 forest or domain, none of these services is enabled by default. You must enable the services manually before running Exchange Server 2003 Installation Wizard.

Before You Begin


When you install Exchange on a new server, only the required services are enabled. For example, Post Office Protocol version3 (POP3), Internet Message Access Protocol version4 (IMAP4), and NNTP services are disabled by default on all of your Exchange 2003 servers. You should enable only services that are essential for performing Exchange 2003 tasks.
