HTTP Error 500.19 - Error Code 0x80070021

Background: Trying to debug WebForms application and get authenticated windows user from AD,

On F5 I get greeted with this amazing page.

Module WindowsAuthenticationModule

Notification AuthenticateRequest

Handler ExtensionlessUrl-Integrated-4.0

Error Code 0x80070021

Config Error This configuration section cannot be used at this path. This happens when the section is locked at a parent level. Locking is either by default (overrideModeDefault="Deny"), or set explicitly by a location tag with overrideMode="Deny" or the legacy allowOverride="false".

Config Source:

   81:         <anonymousAuthentication enabled="false"/>
   82:         <windowsAuthentication enabled="true"/>
   83:         <basicAuthentication enabled="false"

The Windows edition you used is a low end one, which does not even support Windows authentication.

You will have to upgrade to a high end edition such as Professional.

What worked for me is editing the appplicationhost.config file. Changed under the Authentication node: from DENY to ALLOW on the following elements:

<section name="anonymousAuthentication" overrideModeDefault="Allow" />
<section name="windowsAuthentication" overrideModeDefault="Allow" />

Hope this helps!
