.Net 4.0+WCF+WIndows Authentication + IIS

Question

I am trying to host my WCF service in IIS, which supports Windows Authentication. I am able to do it using Framework 3.5, but when I change the Framework to 4.0, it gives the below error.

Security settings for this service require 'Anonymous' Authentication but it is not enabled for the IIS application that hosts this service.

I am able to host the service on development server. But we have to do it using IIS.

<?xml version="1.0"?>
<configuration>
    <system.web>
        <compilation debug="true" targetFramework="4.0">
        </compilation>
        </system.web>
    <system.serviceModel>
        <bindings>
            <basicHttpBinding>
                <binding name="BasicHttpEndpointBinding">
                    <security mode="TransportCredentialOnly">
                        <transport clientCredentialType="Windows"/>
                    </security>
                </binding>
            </basicHttpBinding>
        </bindings>
        <services>
            <service name="Service1">
                <endpoint address="" binding="basicHttpBinding" bindingConfiguration="BasicHttpEndpointBinding" name="BasicHttpEndpoint" contract="IService1">
                    <identity>
                        <dns value="localhost"/>
                    </identity>
                </endpoint>        
            </service>
        </services>
        <behaviors>
            <serviceBehaviors>
                <behavior>
                    <!-- To avoid disclosing metadata information, set the value below to false and remove the metadata endpoint above before deployment -->
                    <serviceMetadata httpGetEnabled="true"/>
                    <!-- To receive exception details in faults for debugging purposes, set the value below to true.  Set to false before deployment to avoid disclosing exception information -->
                    <serviceDebug includeExceptionDetailInFaults="false"/>
                </behavior>
            </serviceBehaviors>
        </behaviors>
        <serviceHostingEnvironment multipleSiteBindingsEnabled="true"/>
    </system.serviceModel>
    <system.webServer>
        <modules runAllManagedModulesForAllRequests="true">
        </modules>
    </system.webServer>
</configuration>

This article has information on how to enable anonymous access for IIS7.

From the UI, you need to do the following:

Open IIS Manager, and left click on your website / application
In the Features pane, double click in Authentication
On the Authentication page, right click on the Anonymous Authentication item and select enable.
