我上class之后，今天早上我所有的应用程序池都停止了。 我可以重新启动它们，但是当我尝试加载网站时，应用程序池再次崩溃。
更新：我已经在GAC中查找下面的错误build议，似乎该文件不存在。 我如何恢复？
更新2 ：我在事件日志中发现了另一个错误
The Module name FastCgiModule path C:\WINDOWS\System32\inetsrv\iisfcgi.dll returned an error from registration. The data is the error. 所以下面的信息从这里http://forums.iis.net/t/1153937.aspx我删除了CGI和我的网站再次工作。 这已经解决了最初的问题，但现在我没有FastCGI，所以我相当确信PHP将不再工作（我目前没有任何PHPtesting）。

我在事件查看器中收到此错误：

昨天晚上我离开工作的时候一切都很好，而且他们做了维护工作，全部都坏了。
