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:
我在基于IIS 7(Windows Server 2008)和SQL Server 2008 R2上运行的基于32位MVC 5的CRUD系统安装到多个服务器中,自2015年8月起提供公司内部网管理服务.几个月来,所有这些系统都运行顺利,没有任何问题.但是,昨天我发现我无法使用此消息访问172.16.1.101服务器上的站点根页面:

>Custom event details: 
有时消息显示\ 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.
主要以为我在IIS系统帐户上有权限错误,我已经完成了对"完全控制"的设置权限而没有成功.
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:
在smarterasp.net上发布包含csc.exe文件的网站时出现问题?
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:
任何人都可以解释为什么ApplicationPoolIdentity选项不适用于这种情况?
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?
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序列化器和Web服务的服务器上遇到过上面描述的YSOD,请帮我解释或描述服务器上已经发生的问题和详细信息.减轻它的方法.
PS:在写入的目录路径上," - "和" - "符号应替换为"\".
在我的虚拟主机上,它帮助我从 web.config 中删除此部分:
