1、运行CMD，进入DOS命令输入C:\Windows\Microsoft.NET\Framework\v4.0.30319输入aspnet_regiis -i
2、如果出错会提示查看安装日志C:\Documents and Settings\Administrator\AppData\Local\ASPNETSetup_XXXXX.log
3、我的出现了 2015-01-25 23:37:53 Failure Installing WMI file:aspnet.mof: InstallMOF failed with HRESULT 80004005: '未指定的错误 '这种情况可能是由于被损坏的wmi库造成的
4、在网上找到一个重建WMI库的批处理http://blog.csdn.net/xuxc/article/details/2230277把以下代码复制存成.bat文件net stop winmgmtc:cd %systemroot%/system32/wbemrd /S /Q repositoryregsvr32 /s %systemroot%/system32/scecli.dllregsvr32 /s %systemroot%/system32/userenv.dllmofcomp cimwin32.mofmofcomp cimwin32.mflmofcomp rsop.mofmofcomp rsop.mflfor /f %%s in ('dir /b /s *.dll') do regsvr32 /s %%sfor /f %%s in ('dir /b *.mof') do mofcomp %%sfor /f %%s in ('dir /b *.mfl') do mofcomp %%secho DONE rebootpause
5、运行后重启，重新安装IIS中的ASP，正常运行！
