[WINDOWS 2000] Problemas al transferir roles

Amigos, nos queremos morir muertos!
para que se entretengan el fin de semana compartimos con ustedes una de nuestras pesadillas. Espero puedan darnos una opnion sobre esto.

Situacion:
Dos servidores, ambos con Windows 2000 Server SP4. Uno con los 5 roles (de ahora en adelante Server A) el otro ADC (Server B). Se realiza la transferencia de roles como indica el kb 255504 (transferir funciones FSMO) de MS TechNet. Se retira el Server A. Al querer unir una estacion de trabajo al dominio o al intentar loguearnos con un usuario de dominio recibimos un mensaje de error indicando que no se encuentra controlador de dominio.

Se reinicia el Servidor B, nos podemos loguear con el usuario administrador de dominio. Y vemos al abrir el AD users and computers que no existe el dominio. Despues de aproximadamente 5 minutos refrescamos y aparece conservando los inconvenientes antes mencionados.

Segun lo leido en otros post de este foro ejecutamos la herramienta dcdiag para ver si podiamos identificar el problema. El resultado del diagnostico es el siguiente:
