一、权限不足
右击网站所在文件夹－－安全选项，加入everyone,internet来宾帐号(IUSR...)用户确定，然后重新启动IIs，未成功请尝试以下方法修复。

二、系统没有开启FSO组件.
运行cmd命令
启用FSO命令：RegSvr32 %windir%SYSTEM32scrrun.dll 
重新注册FSO文件管理 regsvr32 "C:Program FilesCommon FilesSystemadomsado15.dll"

重新注册ADODB.Stream组件

三、如果上述两法仍未解决，则可能是其它原因，不仿试试下面bat批处理代码。将下面代码复制到记事本，另存为 cmd.bat，双击运行就可以了。

echo 正在修复，这个过程可能需要几分钟，请稍候……

四、如果没有解决问题，建议重装IIS，还有问题的情况下就只能重装系统了。
 
补充：
我用办法三批量注册以后，运行iis仍然出错

右键IE桌面图标--->属性--->高级--->去掉“显示友好http错误信息”前面的勾--->再运行的IIS，提示“ASP0201错误”
