文件导入导致我更改我的iis和数据库配置

Question

当我尝试从我的网页导入文件时，我收到某种应用程序池登录错误。因此，我将IIS更改为使用LocalSystem for Identity（但它建议应用程序池标识）。

我改变后发现数据库错误，说NT Authority / System没有权限。因此，我更改了登录安全性并使用dbo权限映射数据库以使其正常工作。

有人能帮助我一些见解吗？该应用程序的其余部分工作正常，没有对IIS和SQL的更改，但就在我执行该文件导入时，它对我咆哮。如何让它以推荐的方式使用应用程序池标识？

使用应用程序池标识运行IIS时从SQL Server获得的错误消息非常准确："Login failed for user 'IIS APPPOOL\Classic .NET AppPool'"

要在SQL服务器上授予访问权限，您可以使用错误消息（IIS APPPOOL\Classic .NET AppPool）中的名称添加登录名，并将其映射到所需的数据库/为其提供适当的权限。这些应用程序池用户无法在搜索向导中搜索，但可以在“登录名”字段中手动输入：

请注意，您通常会创建一个特定的应用程序池，而不是使用内置的Classic .NET AppPool，这个SO帖子提供了更多信息：Separate application pools for ASP.net applications in IIS
