Error al instalar Sharepoint en SBS 2003

Buenas.

Estoy intentando agregar el componente "intranet" (es el Sharepoint) a
mi instalación de Windows SBS 2003 Premium. Al finalizar dicha
instalación me aparece con un mensaje de error como si no se hubiera
instalado (de hecho luego no funciona), y me indica que mire en los
archivos .log para ver el motivo.

En C:\Archivos de Programa\Microsoft Integration\Windows Small Business
Server 2003\Logs\errorlog.txt me encuentro el listado inferior.

¿Alguna pista acerca de dónde mirar para obtener más detalles o cómo
solucionar el problema? En el visor de sucesos no observo nada destacable.

Muchas gracias.
