我們在安裝系統的時候不選擇安裝IIS，等系統安裝完成后手動來做，我們可以使用無人值守的方式自定義安裝IIS 5.0。首先確認你的 Windows 2000的安裝介質是可用的，本例中的安裝介質是光盤，因此只要將安裝光盤插入光驅即可，然后在你的硬盤或者軟盤上創建一個無人值守安裝文件，本例中我們將在D盤創建一個 IIS5install.txt 作為無人值守安裝文件，下面我們看看該文件的內容：
[Components] 所安裝的組件
iis_common = on 公用文件
iis_inetmgr = on IIS管理器
iis_www = on WWW服務
iis_ftp = on FTP服務
iis_htmla = on Web方式的IIS管理器
[InternetServer]
Path="D:inetsrv" Common文件放置位置（如果你是卸載了IIS再手動裝，公用文件還是會位置保持不變）
PathFTPRoot="D:inetPubFTPRoot" FTP的根路徑
PathWWWRoot="D:InetPubwwwroot" WWW的根路徑
將該文件存盤后，運行“sysocmgr /i:%windir%infsysoc.inf /u:d:iis5install.txt”，
不會有提示框出現，系統將自動的為你安裝好IIS，而且Scripts目錄將會在D盤，使用“Unicode解碼目錄遍歷漏洞”也就失效了。
如果你需要安裝更多的IIS組件，以下是一個比較詳細的無人值守安裝文件：
