ArcServer10 安装中提示The following features cannot not be installed due to missing prerequisites"

问题描述：

在win8.1上 安装ArcServer10，安装检查提示 ：The following features cannot not be installed due to missing prerequisites，显示无法有效安装 Service Manager组件，但我已经安装过IIS了。

解决方案：

阅读what I'm missing后，发现对IIS功能的需求有列表。打开“添加或关闭Windows功能”面板，一条条对过去，发现自己少勾了 basic Authentication。改变完成后，重新打开安装界面，则直接检查通过进入安装界面。

附安装功能要求（windows vista及以上版本）
