Servicio Inicio de sesión en red pausado

Hola, Ojalá puedan ayudarme ya que llevo más de una semana intendo
arreglarlo:

Tengo 2 servidores w2003, uno (SERVIDOR) es el DC principal (tiene el
GC, es el RID y el Maestro de Infrestructura), el otro (PERCEVAL) es por
decirlo así el DC secundario.

Desde hace una semana la mayoría de las estaciones de trabajo no se
pueden loguear con el servidor. Utilizo perfiles móviles y DFS, pero no
puedo acceder a la raiz del DFS ni a las carpetas compartidas del
servidor. El servidor tiene el servicio "Inicio de sesión en red"
Pausado. Le doy Inciar al servicio, pero el problema persiste. En los
registros de suscesos me indica que no puede encontrar el Global Catalog
por que el dominio no existe.

DCDIAG me dá la siguiente salida
