Event ID 1083 — IIS W3SVC Performance Counter Availability

Applies To: Windows Server 2008

The Internet Information Services (IIS) World Wide Web Publishing Service (W3SVC) collects HTTP-specific performance counters for Web sites. The W3SVC initializes the counters and receives them from HTTP.sys, the protocol listener for HTTP. If W3SVC is not available, HTTP performance counter data cannot be gathered.
