Exchange Server 2003 es la última versión sobre productos de servidor enfocados en la mensajería electrónica de Microsoft. Algunos lo han definido como la mejora más importante sobre el paquete Exchange Server 2000, con una mejora significativa en el acceso de usuarios moviles, fiabilidad en el servidor, tolerancia a fallos en la mensajeria, en el propio servidor y en la escalabilidad del sistema. La actualizacion a Exchange Server 2003 no es solo una migracion de un entorno a otro; es la oportunidad para beneficiarse de nuevas herramientas con las que las organizaciones pueden mejorar la seguridad en ambos sentidos y disponer de instrumentos vitales para el mantenimiento, la gestion y la recuperacion frente a desastres. Esta obra le muestra los pasos necesarios para planificar y llevar a cabo una migracion satisfactoria hacia este nuevo paquete, aprovechar sus mejoras en las capacidades de comunicacion, seguridad y rendimiento, y dotar a los usuarios de una mayor funcionalidad. De esta manera, podra beneficiarse de las nuevas cualidades de Active Directory, integrandolas con el correo electronico, telefonia movil y funcionalidades de acceso remoto en una herramienta de administracion centralizada. Descubrira ademas aspectos practicos como los servicios de comunicaciones necesarios para la actualizacion, como se combina con los servidores o el uso de varios servidores con redundancia o sobrecarga.
