In Integrated managed pipeline mode, an ASP.NET parameter has been found that does not apply.


I tried installing DotNetOpenAuth SDK- but it didn’t work. It works locally (when I run as localhost), but it doesn’t function when I try to publish it.

I got the following IIS error message:

However, because I am not the owner of the ISS server, I do not have access to it. Is there a way to get around this?

The second option is the one you want to go with.

Make sure the following keys are included in your web.config:

        <validation validateIntegratedModeConfiguration="false"/>

Validation validateIntegratedModeConfiguration=”false”/> solves the problem, however it isn’t acceptable in many cases. After circling this topic a few times, I aim to assist others in not only overcoming but also comprehending the difficulty. (Which becomes more and more important as IIS 6 fades into myth and rumor.)


This problem and the resulting confusion began with the release of ASP.NET 2.0 and IIS 7. IIS 6 had and still has only one pipeline mode, which is the same as what IIS 7+ refers to as “Classic” mode. “Integrated” mode is the second, newer, and recommended pipeline method for any applications running on IIS 7+.

So, what’s the difference between the two? The main distinction is in the way ASP.NET communicates with IIS.

If you still need to use the HTTP Module, setup it as follows (.NET 4.0 framework):

   <modules runAllManagedModulesForAllRequests="true">
       <add name="MyModule" type="[Namespace].[Class], [assembly]"/>
   <validation validateIntegratedModeConfiguration="false"/>

I experienced the same problem, but had a different solution. It entailed going to Control Panel>Administrative Tools>IIS Manager and changing the Managed Pipeline on my App site from Integrated to Classic.

Solution #5

Examine your IIS authentication to see if there are any conflicts. i.e., enabling anonymous authentication and ASP.NET impersonation may both result in an error.
