A. As with Exchange 2000 Server, Exchange 2003 integrates very closely with Windows and uses some of the services and features included with the OS. The core OS components that you need to have installed before installing Exchange 2003 on Windows Server 2003 or Windows 2000 Server are
- The Microsoft .NET Framework
- Microsoft ASP.NET
- The Network News Transfer Protocol (NNTP) service
- The SMTP service
- The World Wide Web (WWW) service
For Windows 2003, you need to manually install the components by performing the following steps:
- From the Control Panel, open the Add/Remove Programs applet.
- Click Add/Remove Windows Components.
- Select Application Server, then click Details.
- Select the ASP.NET option.
- Select Internet Information Services (IIS), then click Details.
- Select the NNTP Service, SMTP Service, and World Wide Web Service options, then click OK.
- Click OK again to close the Application Server dialog box.
- Click Next on the main Windows Components Wizard dialog box and follow the prompts when asked to insert the Windows 2003 installation CD-ROM to install the core components.
Don't forget about any service packs that might also be required. Don't install the Windows 2003 POP3 service--a more robust version is supplied with Exchange 2003.
On Windows 2000, the only core Exchange component you need to install in advance is the NNTP service. Because Win2K doesn't come with the .NET Framework or ASP.NET, Exchange 2003 installs them for you and Win2K installs and enables the SMTP and WWW services when you install the OS.
