我刚刚将一个 ASP.NET MVC 4 应用程序部署到 IIS 7，但是当我浏览它时，我收到以下错误：

Cannot open database "PCSPI" requested by the login. The login failed.
Login failed for user 'NT AUTHORITY\SYSTEM'.

当我将应用程序池标识更改为 networkService 时，我得到：

Exception Details: System.Data.SqlClient.SqlException: Login failed for user 'WORKGROUP\OSCAR-PC$'.    
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: Cannot open database "PCSPI" requested by the login. The login failed.
Login failed for user 'NT AUTHORITY\SYSTEM'.

但是，当我更改应用程序池的身份时，IIS 用于访问 SQL Server 的登录名发生了变化，因此我确定我需要允许访问我的 SQL Server 上的网络服务问题是我似乎无法弄清楚。

请问，如何授予对networkService的访问权限？

任何帮助将不胜感激，在此先感谢

请注意，您可能没有使用网络服务，而是使用系统帐户。'NT AUTHORITY\SYSTEM' 不是网络服务帐户。

转到 Security -> Logins 并创建如下所示的新登录名。然后为网络服务设置用户映射，使其仅具有所需的权限。

SQL Server 是否与 IIS 在同一台服务器上？如果是这样，请转到 SSMS（SQL Server 管理服务器），授予“NT AUTHORITY\NETWORK SERVICE”登录访问权限。

如果 SQL Server 位于单独的服务器上，则必须使用单独的帐户或 SQL Server 登录名。
