我真的很难安装这个。我已经尝试了这里的建议，试图纠正任何可能的腐败。我将磁盘映像安装到“G”以进行离线安装。我还尝试了具有类似结果的在线安装。输出如下：

2013-04-08 23:40:17, Error DISM …客户端 (IE) 对静态 html keep_alive 页面的请求似乎工作得很好，但是在使用相同的 EXACT URL 时，执行负载平衡的网络交换机似乎无法请求相同的页面。来自交换机的 HTTPERR 日志条目给出404-NotFound -。它显然没有进入 IIS 但为什么 HTTPAPI 会拒绝这个？我在哪里可以看到原因代码或错误消息，或其他什么？请帮忙:|

当交换机尝试获取页面时，这每隔几秒钟重复一次。
从我的故障排除中捕获的网络帧：
