Internet Information Services have been evolving over the lasr five years and Windows 2000 has become a sophisticated and robust Web server platform. The latest version, IIS 6.0 will be shipped with Windows Server 2003 and has many new features for Web server management, performance, scalability, reliability, availability and security.

Robustness in IIS 6.0
The underlying architecture of IIS 6.0 has been redesigned to improve flexibility, scalability and reliability. IIS 6.0 adds robustness with a new Worker Process Isolation mode, which allows you to put your web applications into different application pools that share one or more worker processes. The application pools remain independant of each other, so an application failing will not affect other applications or the web service itself.
