C# – WCF Service Windows Authentication Not Working

I have changed Web.Config and the service is working with Anonymous Authentication. Though when Windows Authentication is enabled and Anonymous Authentication is disabled in IIS7.5, it starts giving me following error. Please help.

The authentication schemes configured on the host
('IntegratedWindowsAuthentication') do not allow those configured on
the binding 'basicHTTP' ('Anonymous'). Please ensure that the
SecurityMode is set to Transport or TransportCredentialOnly.
Additionally, this may be resolved by changing the authentication
schemes for this application through the IIS management tool, through
the ServiceHost.Authentication.AuthenticationSchemes property, in the
application configuration file at the
element, by updating the ClientCredentialType property on the binding,
or by adjusting the AuthenticationScheme property on the
HttpTransportBindingElement.

Web.config is as follows:

<?xml version="1.0"?>
<configuration>

<appSettings>
