Security IIS无法启动：错误BC2000

当我尝试在IIS 7.5上启动ASP.net站点时，出现以下错误

BC2000: compiler initialization failed unexpectedly: 0x80070005

四处搜索，我找到了一个可能的解决方案：转到C:\Windows\Temp文件夹的安全设置，并向用户“网络服务”和IIS\U IUSR添加完全控制权限

但我做到了，错误还在继续

在我的计算机中%temp%指向C:\Users\sp\AppData\Local\temp，它们也具有这些权限

我还尝试使用实用程序“aspnet_regiis”重新安装ASP

以下是完整的事件日志条目（应用程序警告1310）：

因此，我所做的工作是将应用程序池的用户更改为计算机管理员（IIS管理器>应用程序池>高级设置>标识）。但这似乎不太安全

所以我的问题是：为什么它不使用“内置帐户”（我尝试了ApplicationPoolIdentity和NetworkService）。

授予用户“网络服务”对文件夹C:\Windows\Temp的完全访问权限请尝试以下步骤-

如果在x64机器上运行，请为默认应用程序池设置True“启用32位应用程序”

在上为网络服务和IIS_IUSR授予完全访问权限

C:\Windows\Temp\

在上为网络服务和IIS_IUSR授予完全访问权限

C:\Windows\Microsoft.NET\Framework\v2.0.50727\ASP.NET临时文件\

---

我最终解决了这个问题，允许对%TEMP%文件夹中的所有人进行完全控制
