Published: July 2003

Abstract

Microsoft Windows® Storage Server 2003 is the latest version of Windows Powered NAS. Built on

the Microsoft® Windows Server™ 2003 operating system, Windows Storage Server 2003 is a

dedicated file server that offers dependable storage while integrating seamlessly with the existing

corporate network infrastructure. Easy to install and manage, Windows Storage Server 2003 offers

outstanding economics. It enables substantial file server consolidation and provides one of the best

platforms for simplified file sharing, backup and replication of businesses essential data.

This white paper introduces the reader to the new and enhanced features of

Windows Storage Server 2003 file server and network attached storage (NAS) technologies.
