好吧我的问题是我已经创建了一个Web应用程序，它访问AD以检查您是否属于某个特定组。它在visual studio（使用IIS Express服务器）中工作正常，但是当我将它部署到真正的IIS服务器时，我得到了这个错误（当调用CredentialsController.Get（）时）：
"Message":"An error has occurred.","ExceptionMessage":"Unknown error (0x80005000)","ExceptionType":"System.Runtime.InteropServices.COMException","StackTrace":"

所以我猜我需要在IIS服务器上配置一些东西，但是无法找到答案。
