Error de DHCP

Buenos días,

En un Controlador de Dominio 2k3 R2 Sp2 se encuentran activos los siguientes
servicios, aparte del servicio de Directorio:

* DNS
* DHCP

Constantemente se me generan los siguientes errores Event Viewer:

Description:
The following problem occurred with the Jet database -1011: Jet database
read or write operations failed. If the computer or database has just been
upgraded, then this message can be safely ignored. If this message appears
frequently, either there is not enough disk space to complete the operation
or the database or backup database may be corrupt. To correct this problem,
either free additional space on your hard disk or restore the database.
After you restore the database, ensure that conflict detection is enabled in
DHCP server properties. For information about restoring the database, see
Help and Support Center. Additional Debug Information: JetBackup.

En el log del DHCP figura el siguiente error:

31,Day,Hour,DNS Update Failed,IP del Host,Nombre del Host,-1,

Consideraciones:

* Espacio en discos del equipo de más de 30 Gb
* Excluida carpeta DHCP de los escaneos del Antivirus.
* El grupo System tiene permisos de Full Control en la carpeta DHCP y en la
raíz de la unidad que aloja la carpeta DHCP.

Es la segunda vez que me ocurre, anteriormente tube que montar la base de
datos DHCP nueva.

¿Se os ocurre algo?.

Muchas gracias por adelantado.
