EXPLANATION    This message should occur only on a down-level computer. Any action to correct the problem should be performed on that computer.  The user accounts database is not configured properly. There may be a conflict between the computer's role, which defines how this server participates in logon security, and the server's record of the name of the primary domain controller.    For example, the role of this computer may be set to PRIMARY while the primary domain controller entry names a different server.    ACTION    Contact your network administrator.
