IIS WAS Availability
Applies To: Windows Server 2008 R2
The Internet Information Services (IIS) Windows Process Activation Service (WAS) is needed for most Web sites because it supports the World Wide Web Publishing Service (W3SVC), which handles HTTP requests. The WAS Process Manager maps application pools to existing worker processes and spawns new instances of W3SVC to host new application pools as needed. If WAS is not available, most Web sites will not start.
