IIS 7.5有什么已知问题吗？当我尝试浏览/启动/查看网站上的任何页面时，我收到以下错误。
HTTP Error 500.19 - Internal Server Error The requested page cannot be accessed because the related configuration data for the page is invalid. Module IIS Web Core Notification BeginRequest Handler Not yet determined Error Code 0x80070021 Config Error This configuration section cannot be used at this path. This happens when the section is locked at a parent level. Locking is either by default (overrideModeDefault="Deny"),or set explicitly by a location tag with overrideMode="Deny" or the legacy allowOverride="false". Config Source 97: </modules> 98: <handlers> 99: <remove name="WebServiceHandlerFactory-Integrated"/>
解决方法
有一个类似的问题，最终找到这篇文章：

基本上applicationHost.config的处理程序部分被锁定：
是
<section name="handlers" overrideModeDefault="Deny" />
我改变了
<section name="handlers" overrideModeDefault="Allow" />
它工作。
也值得检查所有asp.net角色是否已安装，请参阅link text。
