fix

Directory and Resource Administrator (DRA) will not be able to manage an NT4 domain if the Primary Domain Controller (PDC) for the domain is not available.  The PDC in an NT4 domain is the only domain controller that maintains the writable (master) copy of the SAM database.  All other domain controllers (Backup domain controllers) in an NT4 domain maintain a replica (read-only) copy of the SAM database.  Due to this design restriction in Microsoft Windows NT, a DRA server will not be able to manage the NT4 domain unless the PDC is brought back online or another domain controller is promoted to the PDC. Thus, the preferred domain controller for NT4 domains is always automatically configured to use the PDC.  If a new PDC is promoted DRA will begin using it as the new preferred domain controller once a Domain Cache Refresh has taken place or if the NetIQ Administration Service has been restarted.
