我正在 Windows Server 2012 上进行应用程序测试，以检查我们的 Web 应用程序（在 .Net 4 中）的兼容性，并且在加载任何 ASPX 页面时遇到问题。我曾多次尝试从服务器管理器中卸载并重新安装所有 .Net、IIS 和 ASP.Net 角色。我还发现它aspnet_regiis不再适用于 Server 2012，它只是给出了使用角色/功能页面的消息。我很茫然，还有其他人尝试过 IIS 8 吗？

我收到以下消息：

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.

Most likely causes:
•It is possible that a handler mapping is missing. By default, the static file handler processes all content.
•The feature you are trying to use may not be installed.
•The appropriate MIME map is not enabled for the Web site or application. (Warning: Do not create a MIME map for content that users should not download, such as .ASPX pages or .config files.)
•If ASP.NET is not installed.

Things you can try:
•In system.webServer/handlers: ◦Ensure that the expected handler for the current page is mapped.
    ◦Pay extra attention to preconditions (for example, runtimeVersion, pipelineMode, bitness) and compare them to the settings for your application pool.
    ◦Pay extra attention to typographical errors in the expected handler line.

•Please verify that the feature you are trying to use is installed.
• Verify that the MIME map is enabled or add the MIME map for the Web site using the command-line tool appcmd.exe. 
    1.To set a MIME type, use the following syntax: %SystemRoot%\windows\system32\inetsrv\appcmd set config /section:staticContent /+[fileExtension='string',mimeType='string']
    2.The variable fileExtension string is the file name extension and the variable mimeType string is the file type description.
    3.For example, to add a MIME map for a file which has the extension ".xyz": appcmd set config /section:staticContent /+[fileExtension='.xyz',mimeType='text/plain']
    Warning: Ensure that this MIME mapping is needed for your Web server before adding it to the list. Configuration files such as .CONFIG or dynamic scripting pages such as .ASP or .ASPX, should not be downloaded directly and should always be processed through a handler. Other files such as database files or those used to store configuration, like .XML or .MDF, are sometimes used to store configuration information. Determine if clients can download these file types before enabling them. 
 •Install ASP.NET.

好吧，在过去几天解决了这个问题之后，我将 VM 重置为我在完成操作系统安装后立即拍摄的基本快照。我按照我在第一次运行中记录的完全相同的步骤安装 IIS 和应用程序开发功能，然后安装了我的应用程序，现在它可以工作了。我不知道它为什么或如何在以前没有的地方工作，但至少它现在正在工作。
