ASP.NET error page does not work remotly

I have problem with ASP.NET error page within my A开发者_Python百科SP.NET MVC application. When I browser to my application and exception happen then I just get this:

Runtime Error Description: An application error occurred on the server. The current custom error settings for this application prevent the details of the application error from being viewed remotely (for security reasons). It could, however, be viewed by browsers running on the local server machine.

Details: To enable the details of this specific error message to be viewable on remote machines, please create a tag within a "web.config" configuration file located in the root directory of the current web application. This tag should then have its "mode" attribute set to "Off".

But I have in my Web.config so seems that this is not a solution, so what's the correct solution to have entire stack trace displayed on the page? I don't really want to implement at this point my own error page.

If you turn on health monitoring, you can get more of the details of this message. Also, are you using IIS? Which version? Anything below IIS 7 needs a special setup.
