The HTTP SSL service runs as LocalSystem in a shared process. It shares an executable file with other services. If the HTTP SSL fails to load or initialize, the error is recorded into the Event Log. Windows XP startup should proceed, but a message box is displayed informing you that the HTTPFilter service has failed to start.
HTTP SSL will not start, if the HTTP service is stopped or disabled.
