Windows Small Business Server

Windows Small Business Server 2003 is a server solution that provides small businesses with great features, such as e-mail, secure Internet connectivity, business intranets, remote connectivity, support for mobile devices, file and printer sharing, backup and restore capabilities, and an application platform for collaboration. Windows Small Business Server 2003 is available as a full product in either the standard or premium edition, which includes five CALs.

Both editions of Windows Small Business Server 2003 have two types of Client Access Licenses (CALs) to choose from: device-based (device CALs) or user-based (user CALs). These options offer you the flexibility to choose the licensing that best suits the needs of your organization.

Device CALs
With device CALs, you acquire a CAL for every device that accesses your server. With this option, any user can access the server on the licensed device. Device CALs might make the most economic and administrative sense for an organization that has multiple users for one device, such as shift workers.

User CALs
With user CALs, you acquire a CAL for every named user accessing your server. The licensed users can access the server from any device. User CALs might make the most sense for an organization that has many roaming employees that need access to the corporate network from mobile devices and/or employees who use multiple devices to access the network.
