c# - 异常 : User does not have permission to perform this action

Question

我一直在 visual studio 中使用我的网站 (ASP.NET MVC)，但现在我想将它托管在我的服务器上。我从 visual studio 发布到要使用的网络共享上。服务器正在运行 Windows Home Server、IIS 6 和 SQL Server 2008 R2 (express)。

在 Microsoft SQL Server Management Studio 中，我附加了数据库并确保用户 IUSR_SERVER 是数据库的所有者。我还确保用户网络服务具有访问权限。

该网站在 IIS 中配置为以 IUSR_SERVER 匿名运行。我已授予对 IUSR_SERVER 以及文件系统中的网络服务的写入和读取访问权限，并确保没有任何内容是只读的。

web.config 有这个连接字符串:

        <connectionStrings>
    <remove name="ApplicationServices" />
  <add name="ApplicationServices" connectionString="Data Source=.\SQLExpress;Integrated Security=True;Initial Catalog=MyDatebase"
   providerName="System.Data.SqlClient" />
     </connectionStrings>

但是，我无法浏览我的网站。我只得到这个错误:

Server Error in '/' Application.

User does not have permission to perform this action. Description: An unhandled exception occurred during the execution of the current web request. Please review the stack trace for more information about the error and where it originated in the code.

Exception Details: System.Data.SqlClient.SqlException: User does not have permission to perform this action.

感觉我什么都试过了。非常感谢您在这方面的帮助。

原来问题是我的 DataContext 使用它自己的连接字符串，它不在 web.config 中。因此，它从未更改，无法建立连接。我更改了我的代码，以便我的数据上下文使用来自 web.config 的字符串并且它有效:)
