[] Tarea programada
No funciona con el usuario system, hay que poner con uno con
privilegios en el AD
Lo ideal sería ejecutarlo cada hora y que solo envía si hay errores. Yo lo hago una vez al día porque en principio no tengo problemas de sincronización y durante el día si lo tuviese seguro que tendría algún otro indicador que me alertaría.
