You have already made a connection to computer name as a user who is not a supervisor. To add a NetWare server to the domain, you must be logged on as a supervisor to that server. Please remove the connection before adding the server to the domain.
To add a NetWare server to a Windows 2000 domain, you must have supervisor rights on the Netware server that you are connecting to. To add the specified server to a Primary Domain Controller (PDC) you must also be a member of the administrative group on the PDC.
If you have logged on as a user, remove the connection and try again. If you continue to get this message, verify that you have administrative privileges on both the Netware server that you are connecting to and the Windows 2000 primary domain controller.
