I configured the IIRF in my web server and trying to proxy the URLS and when executed the request it doesn't work. I ran through the Event Log in server and find the below warning logged into event log.

The description for Event ID ( 1 ) in Source ( Ionic Isapi Rewriting Filter ) cannot be found. The local computer may not have the necessary registry information or message DLL files to display messages from a remote computer. You may be able to use the /AUXSOURCE= flag to retrieve this description; see Help and Support for details. The following information is part of the event: IIRF: event ID 1, Invalid Parameter: expression((null)) func((null)) file((null)) line(0).

What would be the problem.

Yes, the messages in the Event log are not very clear. 

Event ID = 1 indicates an "invalid parameter".   I understand that this may not clarify things for you. 

What it usually comes from is a bug in IIRF.

To determine whether that is the case, I will need:

  • the version of IIRF you are using
  • the IIRF log file that is generated when the event in question appears in the event log.  You should use LogLevel=3
