Tenemos un servidor de archivos de Windows 2003 con un DC de Windows 2008 R2. Durante un tiempo esto ha estado funcionando bien, pero ahora la hora en el servidor de archivos está cambiando y ya no se sincroniza. El servidor de archivos es una máquina virtual. Lo curioso es que tiene un servidor "socio" en un sitio diferente, también una máquina virtual win 2003, que no tiene problemas de tiempo.
Aquí hay una parte del registro de w32time en el servidor de archivos:

¿Es correcta mi interpretación de que w32time no puede corregir la hora porque la diferencia es demasiado grande? ¿Cómo puedo arreglar esto? Estoy un poco desconcertado por las razones de esto, ya que los otros hosts de la red no tienen problemas de tiempo.
