IIS ISAPI Extension dll not working
I have been trying to get this ISAPI Extension settings correct in IIS, with no success.
In IIS under the Machine name -> ISAPI and CGI Restrictions I have included my dll with the correct path c:\inetpub\scripts\CreditN
I also have the Allow unspecified CGI module and Allow unspecified ISAPI modules boxes ticked.
In the Handler Mappings for the option ISAPI-dll my executable is set as C:\inetpub\scripts\CreditN
In the Access tab->Execute is chosen.
In the Default Web Site section-> Virtual Directories, my correct path is set here:
Physical Path: C:\inetpath\scripts
Also in Control Panel->Programs and Features->Turn Windows features on or off->IIS -> Application Development Features, all options are ticked (CGI,ISAPI Extensions,ISAPI Filters...).
The error message that I get when running the dll on Internet Explorer is:
HTTP Error 500.0 - Internal Server Error
There is a problem with the resource you are looking for, so it cannot be displayed.
Module IsapiModule
Notification ExecuteRequestHandler
Handler ISAPI-dll
Physical Path C:\inetpub\scripts\CreditN
I have been playing around with the IIS settings for a while now and unable to get this working.
The code is correct because it used to work on a different machine running on Windows Vista.
My current OS is Windows 7.
I am missing some setting or registration and I can't figure it out. Any help will be highly appreciated.

I have written it myself using Visual C++ 9.
This dll works on some boxes which uses IIS 6.
It doesn't want to work on my Windows 7 box with IIS 7.5.
I have checked and double checked all the IIS settings and can't seem to find what is causing the web page from not picking up the ISAPI Extension dll.

Okay I managed to find the problem.
In my web.config file I had to set:
<system.web>
<identity impersonate="false" />
</system.web>
All my ISAPI dlls are working fine now.
Thanks for the response.

where does that dll come from? Did you write it yourself, or is it some third party component?
Cheers.
