Windows Storage Server 2003 is a Network Attached Storage (NAS) operating system, built upon the Microsoft Windows Server 2003 operating system. Windows Storage Server 2003 lets original equipment manufacturers (OEMs) build appliances optimised for file serving, since applications unnecessary to the file serving and storage tasks are not activated.

Storage Server NAS devices are usually run headless (without monitor, keyboard or mouse) and can be managed through a Web-based user interface. Designed for ease of deployment and seamless integration into the existing network, Windows Storage Server 2003 can provide expanded storage capacity to users on the network in less than 15 minutes.

The Storage Server NAS solution is especially appropriate for organizations that do not want to put expensive IT resources into setting up multiple file servers and managing them.
