If you have application that works and 1 that doesn't on the same server then you need to identify why the other application isn't working.
Your server admin should be able to tell you what's in the CGI restriction list.
appcmd list config /section:isapiCgiRestriction
Setup a test server, match the CGI restrictions, and tweak your appliction until it works properly.
