WCF服务Windows身份验证不起作用

我更改了Web.Config，该服务正在使用匿名身份验证 . 虽然在IIS7.5中启用了Windows身份验证并禁用了匿名身份验证，但它会开始给我以下错误 . 请帮忙 .

主机上配置的身份验证方案（'IntegratedWindowsAuthentication'）不允许在绑定'basicHTTP'（'Anonymous'）上配置的身份验证方案 . 请确保将SecurityMode设置为Transport或TransportCredentialOnly . 此外，可以通过IIS管理工具，通过ServiceHost.Authentication.AuthenticationSchemes属性，在元素的应用程序配置文件中更改此应用程序的身份验证方案，通过更新绑定上的ClientCredentialType属性，或通过调整HttpTransportBindingElement上的AuthenticationScheme属性 .

Web.config如下：
