I’m trying to leave an application authenticated by Windows. But when I change the settings on IIS with anonymous authentication disabled as per the image below: enter image description here I have the following mistake:

[Messagesecurityexception: The HTTP request is not authorized in the 'Anonymous' client authentication scheme. The authentication header received from the server was 'Negotiate,NTLM'.]

I’m using a WCF, I’ve made several changes to webconfig but always comes back to this error.

Does anyone have any idea what it might be?

Add this snippet to web.config. If you are going to use Windows authentication, it is not necessary to have the personification of ASP.NET active

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

  • I deactivated ASP.NET personification, and added this code on web.config, but I still have the same error.

  • @Can you solve it? I have a hunch for this problem. If you still need it, I will need to confirm some things with you

  • I still can’t fix it.

  • If you right-click on "Windows Authentication" and then click on providers, what appears?
