这是我的第一个问题，如果我有一些语法错误，请向我道歉。

问题描述：

我在IIS 7（Windows Server 2008）上运行32位基于MVC 5的CRUD系统。 SQL Server 2008 R2安装在多个服务器中，自2015年8月起提供公司内部网管理服务。 几个月来，所有这些都顺利运行，没有任何问题。但是，昨天我发现我无法使用以下消息访问172.16.1.101服务器上的站点根页：

>Custom event details:

有时消息会显示\ Temporary ASP.NET Files \ tls目录，而不是\ Temporary ASP.NET Files \ root目录。

IIS 7服务器默认配置为默认状态和单个池，没有任何正在运行的Web服务（仅限基本配置），包括XML（解除）序列化程序。

主要认为我在IIS系统帐户上有权限错误，我已经设置了“完全控制”权限但没有成功。

因此，根据消息在服务器端预期丢失文件编译，尝试通过此命令在CMD上手动编译cmdline文件

  

csc.exe / noconfig / fullpaths @“C：\ Windows \ Microsoft.NET \ Framework \ v4.0.30319 \ Temporary ASP.NET Files \ root-（随机8位十六进制） - （随机8位十六进制） ） - （随机8-char base64）.cmdline“

提供错误：

  

致命错误CS2021：文件名'@C：\ Windows \ Microsoft.NET \ Framework \ v4.0.30319 \ Temporary ASP.NET Files \ root-（随机8位十六进制） - （随机8位十六进制） - （随机8-char base64）.cmdline'太长或无效

     

错误CS2011：错误打开响应文件'c：\ Windows \ Microsoft.NET \ Framework \ v4.0.30319 \ root-（随机8位十六进制） - （随机8位十六进制） - （随机8- char base64）.cmdline' - '系统找不到指定的文件。 “

不会放弃，我对这个问题进行了谷歌搜索，并在SO上发现了相关的类似问题：

https://stackoverflow.com/questions/37146958/an-unhandled-exception-was-generated-during-the-execution-of-the-current-web-re

但是，我没有安装“Microsoft.CodeDom.Providers.DotNetCompilerPlatform”软件包，也没有在为实时服务器实现编译项目时使用SOAP，并且在web.config上已经有'identity impersonate =“true”'属性但没有用

接下来，我使用“高级设置”选项配置了与该站点对应的IIS应用程序池，将“身份”部分从“ApplicationPoolIdentity”更改为“LocalSystem”，有趣的是，访问根页面的YSOD消失了。我试图将它改回“ApplicationPoolIdentity”并且YSOD转回来了。

即使问题已经通过LocalSystem身份暂时解决，我仍然很好奇为什么错误发生时没有任何系统故障的迹象。我想问两个问题：

  1. 有人可以解释为什么ApplicationPoolIdentity选项在这种情况下不起作用吗？

  2. 我可以采取哪些措施来缓解其他服务器的这个问题，即使设置了默认设置和ApplicationPoolIdentity？

    3. tl; dr ：在IIS 7服务器上使用默认配置的ApplicationPoolIdentity工作到昨天我在没有应用XML序列化器或Web服务的服务器上遇到上述YSOD，请帮我解释或描述服务器上已经发生了什么问题以及减轻它的方法。

    PS：在写入的目录路径上，“ - ”和“ - ”符号应替换为“\”。

我知道这已经很老了，但是过去几天我遇到了这个问题，我不得不深入Google搜索才能找到解决方案。

以防万一其他人遇到此问题，并且找不到任何对您有用的文件夹删除。微软的这个工具可以为您完成工作！

在我的情况下，向本地帐户“ IIS_IUSRS”添加权限以在Web应用程序正在解决的目录下读取和执行该问题。

答案 4 :(得分：0)

在我的虚拟主机上，它帮助我从web.config中删除了此部分：
