C# System.Data.SqlClient.SqlException:用户登录失败'；NT授权\匿名登录'；

伙计们。我是c#的新手，如果这个问题听起来很傻，我想道歉。当我尝试在浏览器中的本地主机上部署mvc应用程序时，我不断遇到上述错误。我使用了IIS服务器。我通过服务器exporer连接了数据库，系统运行良好

如果我从Visual Studio运行它，效果会很好。当我在浏览器上输入localhost时，我会得到应用程序默认登录页，这很好，但当我提交数据时会出现错误，这使我认为这是数据库连接问题。我已经试着对此进行研究，但我还没有找到一个适合我的答案。请尽快帮助我，因为我卡住了。我正在使用windows身份验证，因此请帮助我，但请帮助我使用windows身份验证进行连接，并指出我可以更改哪些内容，以确保成功后使用数据库密码和用户身份验证进行连接

先走一步

下面是我的连接字符串

<add name="SA1Entities1" connectionString="metadata=res://*/Models.SA1.csdl|res://*/Models.SA1.ssdl|res://*/Models.SA1.msl;provider=System.Data.SqlClient;provider connection string=&quot;data source=NPX4912PLUS;initial catalog=SA1;integrated security=True;MultipleActiveResultSets=True;App=EntityFramework&quot;" providerName="System.Data.EntityClient" />

比赛情况如下：

Server Error in '/' Application.
