Question

在 Windows 2000 服务器 (IIS 5) 上托管 ASP.NET 2.0 Web 应用程序之后。我无法浏览网站。

浏览器上显示了以下错误消息，并添加了三个事件日志条目...

任何想法...

为什么访问 System.Web 程序集会抛出 System.IO.FileLoadException？

Answer 1

我发现，当网站文件夹被复制到服务器时，它继承了父文件夹的安全权限，只有管理员、管理员和系统帐户的权限。

我加了

• IUSER_MACHINENAME(Internet guest 帐户)
• ASPNET(ASP.NET 机器帐户)

具有读取和执行、列出文件夹内容和读取权限。

虽然问题解决了，但还是有一些疑问

从第三个事件日志条目可以清楚地看出，ApplicationManager 无法创建 System.Web 程序集中的 HostingEnvironment。

由于为 System.Web 抛出 FileLoadException，因此 ASP.NET 工作进程似乎无权访问 GAC 文件夹。
