我们在安装系统的时候不选择安装IIS，等系统安装完成后手动来做，我们可以使用无人值守的方式自定义安装IIS 5.0。首先确认你的 Windows 2000的安装介质是可用的，本例中的安装介质是光盘，因此只要将安装光盘插入光驱即可，然后在你的硬盘或者软盘上创建一个无人值守安装文件，本例中我们将在D盘创建一个 IIS5install.txt 作为无人值守安装文件，下面我们看看该文件的内容：
[Components] 所安装的组件
iis_common = on 公用文件
iis_inetmgr = on IIS管理器
iis_www = on WWW服务
iis_ftp = on FTP服务
iis_htmla = on Web方式的IIS管理器
[InternetServer]
Path="D:inetsrv" Common文件放置位置（如果你是卸载了IIS再手动装，公用文件还是会位置保持不变）
PathFTPRoot="D:inetPubFTPRoot" FTP的根路径
PathWWWRoot="D:InetPubwwwroot" WWW的根路径
将该文件存盘后，运行“sysocmgr /i:%windir%infsysoc.inf /u:d:iis5install.txt”，
不会有提示框出现，系统将自动的为你安装好IIS，而且Scripts目录将会在D盘，使用“Unicode解码目录遍历漏洞”也就失效了。
如果你需要安装更多的IIS组件，以下是一个比较详细的无人值守安装文件：
