背景：尝试调试 WebForms 应用程序并从 AD 获取经过身份验证的 Windows 用户，
在 F5 上，我被这个惊人的页面所欢迎。
模块 WindowsAuthenticationModule
通知 AuthenticateRequest
处理程序 ExtensionlessUrl-Integrated-4.0
错误代码 0x80070021
配置错误 此配置部分无法在此路径使用。 当该部分在父级别上被锁定时，就会发生这种情况。 锁定可以是默认的（overrideModeDefault =“Deny”），也可以通过具有 overrideMode =“Deny” 或遗留 allowOverride =“false”的位置标记来显式设置。
配置来源：
81: <anonymousAuthentication enabled="false"/>
82: <windowsAuthentication enabled="true"/>
83: <basicAuthentication enabled="false"
我的 Web.config（只是不同的名称）

change the connection string named "DefaultConnection" to connect to an instance

我四处查看并检查了我的设置，发现在我的IIS->万维网服务->安全性下没有Windows身份验证。
即使禁用匿名身份验证，我这里也没有它。
我需要检查或者做什么才能解决问题？由于我还是一个新手，我不知道该怎么做。
