ASP.NET 401 - Unauthorized, Valid Account

Question

It's a little complicated

I am running a .NET 4.0 site on IIS 7.5 using Windows authentication and starting the site in a custom application pool with Identity set to the domain administrator account (you need to run scripts with administrator rights).

My webconfig is as follows:

<authentication mode="Windows"/> <authorization> <deny users="?"/> </authorization> </system.web> 

Whenever I enter a site using IE8 (it should authenticate me automatically), it asks for my credentials, and I provide some common domain user credentials, they refuse me until it gives me an error: 401 - Unauthorized: access denied due to incorrect credentials.

However, if I put his domain administrator credentials, I’m granted access, good for me, but bad for my users :)

What's happening?

Some common problems people face are: Installing NTML as the default authentication provider, without cubes. And the wwwroot folder is not used

Answer 1

• After removing the IIS role and creating it again.
• Configure a new application pool using the correct credentials and .NET 4.0
• Run this hotfix again http://www.gotknowhow.com/articles/fix-bad-module-managedpipelinehandler-in-iis7
• Re-creating my site default site
• Convert it to application
• Configure to use the correct pool

Problem solved itself

Answer 2

Have you enabled Windows authentication in your IIS7.5 for the site in your virtual directory?
