I have some trouble indexing files using the VirtualPathNativeProvider. I am also using VirtualPathVersioningProvider in the same solution for other files, and they all get indexed and I get searchresults for these files. No luck with the VirtualPathNativeProvider though. 

I am logging with log4net on the server where the index-service is running, and I get this error message (where "Filkataloger" is the name of the native folder in episerver.config): 

2011-10-21 10:06:38,915 [7] EPiServer.IndexingService.MainService.Run(:0) - Failed to index configuration 2
System.Exception: Cannot find root in database: /Filkataloger
   at EPiServer.IndexingService.ObjectStoreManager.IsChildOfConfiguration(IItem item)
   at EPiServer.IndexingService.MainService.Index(Configuration config)
   at EPiServer.IndexingService.MainService.Run()

This is the setup in EPiServer.IndexingService.exe.config:
<add connectionString="Data Source=*******;Initial Catalog=******;Persist Security Info=True;User ID=*******;Password=****;"
             providerName="System.Data.SqlClient"
             filePath="E:\Episerver_Fileshare\VPP\Intranett\Filkataloger"
             databaseClient=""
             itemRoot="/Filkataloger" />

This is the setup in episerver.config:
<add showInFileManager="true" virtualName="Filkataloger" virtualPath="~/Filkataloger/" indexingServiceCatalog="Web" bypassAccessCheck="false" maxVersions="5"
             physicalPath="\\*******\e$\Episerver_Fileshare\VPP\Intranett\Filkataloger" name="Filkataloger" type="EPiServer.Web.Hosting.VirtualPathNativeProvider,EPiServer" />    	
 
 Has anyone any idea of what I am doing wrong here? I am trying to use the EPiServer CMS Indexing Service to do the job. This is supposed to work right, or do I have to use Microsoft indexing service?

Any help would be appreciated.
