Windows Server 2008 comes with Internet Information Services 7.0 (IIS7), a Web server and security-enhanced, easy-to-manage platform for developing and reliably hosting Web applications and services. A major enhancement to the Windows Web platform, IIS7 includes a componentized architecture for greater flexibility and control.

IIS7 also provides simplified management, powerful diagnostic and troubleshooting capabilities that save time, and comprehensive extensibility. Internet Information Server IIS7 together with the .NET Framework 3.0 provide a comprehensive platform for building applications that connect users and data, enabling them to visualize, share, and act on information. Additionally, IIS7 plays a central role in unifying Microsoft's Web platform technologies—ASP.NET, Windows Communication Foundation Web services, and Windows SharePoint Services.
