Many of the design changes in Internet Information Services (IIS) 6.0 directly address the need to secure the World Wide Web Publishing Service (WWW service) as a whole, and Web and FTP sites in particular. You might experience errors if you have not enabled certain features or services that are locked, or disabled, by default. This topic describes some of the symptoms of these errors and the processes to remedy them (or a link to a topic that describes how to remedy the error). For a comprehensive list of changes in IIS 6.0, including a list of security changes and a brief explanation of the new process model, see What's Changed in IIS 6.0.
