Microsoft® Exchange Server 2007 setup cannot continue because the Microsoft Windows Server™ 2003 Simple Mail Transfer Protocol (SMTP) service is installed on this computer.

  1. On the Start menu, click Control Panel.

  2. Double-click Add or Remove Programs.

  3. Click Add/Remove Windows Components.

  4. In the Components list, select the Application Server check box and then click Details.

  5. Select Internet Information Services Manager and then click Details.
