IIS 10中找不到HTTP错误404.3- [英] HTTP Error 404.3-Not Found in IIS 10

问题描述

我使用IIS 10，Windows 10和VisualStudio2015.

将WEB应用程序添加到IIS站点并打开它后，出现错误:

  HTTP错误404.3-找不到由于扩展程序配置的原因，无法提供您请求的页面.如果页面是脚本，请添加处理程序.如果应下载文件，请添加一个MIME映射. 

我从以下位置安装了IIS子组件:

 控制面板->程序和功能->打开或关闭Windows功能 

如该

但这并没有帮助我，但我仍然遇到相同的错误.

任何想法为何我总是不断出现此错误，也许与 IIS 10 的版本有关?

解决方案

对于WCF Web服务，我也遇到了同样的问题.对其进行了如下修复:打开-打开或关闭Windows功能，然后启用HTTP激活

I use IIS version 10 and Windows 10 and VisualStudio 2015.

After I add WEB application to IIS site and open it I get error:

HTTP Error 404.3 - Not Found

The page you are requesting cannot be served because of the extension configuration. If the page is a script, add a handler. If the file should be downloaded, add a MIME map.

I installed IIS sub components from:

Control Panel -> Programs and Features -> Turn Windows features on or off

As described in this post by Mekanik.

Here is screenshot of installed sub components:

But it didn't helped me and still I get the same error.

Any Idea why I keep getting this error above maybe it has something to do with version of IIS 10?

解决方案

I had the same problem for a WCF web service. Fixed it as follows: Open - Turn Windows Features ON or OFF, then Enable HTTP Activation
