IIS元数据库可能坏了。。测试一下。
Try to enumerate metabase:
1. Open a command prompt and change to the C:\Inetpub\Adminscripts folder.
2. At the command line, type "cscript adsutil.vbs enum " (without the
quotation marks).
If this command is successful, it enumerates the settings in the
metabase.
If the command is not successful, you receive the -2146893792
(0x80090020) error code.
假如有备份,把数据回复。
如果没有,参考
