I had installed Windows 2003 Server in a new system and made the AD up. After that i wanted to migrate first my users from a Windows NT domain and i tried that through the AD migration tool (ADMT). It gives and error -- Access is denied ( Error code=5, domain = My NT Domain name ) . I would like to know what this means and also how do i know whether i have installed in native or mixed mode the windows 2003 .
