Comment: The ISAPI filter can fail to load for a number of reasons - the configuration file may contain a typo the IIS configuration may not have been set up correctly... However it is rarely mentioned that folder permissions need to be granted for the Apache folders containing the ISAPI DLL configuration libraries and the folder where the logs will be written. If everything else seems to be configured correctly this will probably solve the problem.

You will get event ID’s 2214 and 2268 in the application log if the file permissions are not set up right and the ISAPI filter will fail to load (red downward arrow) in the IIS Manager. These are the minimum required permissions for the local accounts described
