[AccessD] Open Database Method

I hit a snag with a process I'm putting together.  I'm trying to use the OpenDatabase method in an Access 2000 database to open a second Access 2000 database so that I can enumerate indices.  I want to delete indices and reindex on demand from the first database.  I'm getting an error that the database is an unrecognized format.  I can open the 2nd database without problem if I go to it directly.  
   
  Here is the code I'm using.  Ideas?  Has anyone done this before?
   
  Thanks,
Jeremy
   
    Sub TestThis()
    Dim wrkJet As DAO.Workspace
    Dim db As DAO.Database
    Dim sDB As String
    
    sDB = "C:\Test\BackEnd.mdb"
    
    Set wrkJet = CreateWorkspace("wrkSpace", "admin", "", dbUseJet)
    Set db = OpenDatabase(sDB, True)
   
      Set db = Nothing
    Set wrkject = Nothing
    
End Sub
