Authentication in Web Application Toolkit for FAQs

I'm modifying this for a website: http://archive.msdn.microsoft.com/toolkitfaqs

The current authentication was using forms to secure the faqs/admin directory, I want to use windows authentication.

I have two webconfigs, 1 at the root level and one inside the faqs/admin directory.

Root Level config has this:

<syst开发者_C百科em.web>
   <authentication mode="Windows" /> 
</system.web>
<location path="Faq/Admin">
      <system.web>
           <authorization>
                <allow roles="Domain\group1, Domain\group2" />
            <deny users="*" />
            <deny users="?"/>
       </authorization>
  </system.web>
</location>

The web config inside the faqs/admin directory has this:

<configuration>
<system.web>
  <httpHandlers>
    <add path="*.aspx" verb="*" type="System.Web.HttpNotFoundHandler" validate="true"/>
  </httpHandlers>
</system.web>
</configuration>

When I try to hit the faqs/admin directory I receive this error:

Access is denied. Description: An error occurred while accessing the resources required to serve this request. The server may not be configured for access to the requested URL.

Error message 401.2.: Unauthorized: Logon failed due to server configuration. Verify that you have permission to view this directory or page based on the credentials you supplied and the authentication methods enabled on the Web server. Contact the Web server's administrator for additional assistance.

Does this work differently in mvc projects? Or what am I doing wrong?

Thanks in advance!
