一、错误情况

环境：win7+iis7.0

DirectoryEntry配置IIS7出现如下错误

或者是

下面一段代码在IIS6.0下运转正常，但IIS7.0下运转会出错:

System.DirectoryServices.DirectoryEntry iisServer; iisServer = new System.DirectoryServices.DirectoryEntry("IIS://localhost/W3SVC/1"); System.DirectoryServices.DirectoryEntry rootFolder = iisServer.Children.Find("Root","IIsWebVirtualDir");//此处抛出异常

异常内容如下:

[System.Runtime.InteropServices.COMException] {"Unknown error (0x80005000)"}  System.Runtime.InteropServices.COMException

Unknown error (0x80005000)    at System.DirectoryServices.DirectoryEntry.Bind(Boolean throwIfFail)    at System.DirectoryServices.DirectoryEntry.Bind()    at System.DirectoryServices.DirectoryEntry.get_IsContainer()    at System.DirectoryServices.DirectoryEntries.CheckIsContainer()
