| Event Id | 22 |
| Source | W3SVC |
| Description | An attempt was made to load filter C:\WINNT\system32\inetsrv\sspifilt.dll on a server instance but it requires the SF_NOTIFY_READ_RAW_DATA filter notification so it must be loaded as a global filter. For additional information specific to this message please visit the Microsoft Online Support site located at: http://www.microsoft.com/contentredirect.asp. |
| Event Information | The following information from a newsgroup post will be helpful to understand this event: A filter that was installed on a W3 instance of IIS will not load when it requires processing of raw information from INETINFO.EXE. This filter can only be loaded at the IIS top level (not at virtual server level). Example: the "sspifilt.dll" that is required to process SSL (https) requests. |
