I have a website written using MVC3 where the backend is a 3rd party system written in Cobol.
The webserver should starts the Cobol runtime through an interop dll and thereafter performs a call to the relevant program.
When I run this setup from Visual Studio using IIS Express then everything works fine.
When I run it using "real" IIS5 however, the site hangs on the first call to the backend.
As far as running processes go, I can see that the runtime exe file is running meaning the initial call was made and permissions seem to be ok.
I have tried setting all permissions for the user on both the involved directories and files and also on the COM service.
What else could I be missing here? Is there any additional trace I could use?
