problemas con AD (roles)

Estoy teniendo estos errores al ejecutar DCDIAG
Necesito que me den una mano para poder soliucionarlos.
tenía en su momento 2 servidores W2003 Server en el dominio
oficina.com.ar, el primero (mydomain-1) se rompió y al parecer el segundo
(mydomain-2) no tomó todos sus roles, alguna sugerencia para eliminar este
error?

Muchas Gracias, Christian
