Event InformationThe 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.
