Overview

The Microsoft Windows Small Business Server 2011 Standard Client Access License (1 Device) is a licensing product rather than a piece of software. It grants one device — a PC, laptop, thin client, or other endpoint — the legal right to connect to and consume services from a Windows Small Business Server 2011 Standard environment. For organizations that rely on SBS 2011 for Active Directory, Exchange, SharePoint, and file services, each accessing device must hold a valid CAL to remain in compliance with Microsoft's volume licensing terms.

As a device CAL rather than a user CAL, this license is attached to the hardware itself. This model is cost-effective in environments where multiple employees share a single workstation, since one CAL covers the device regardless of who logs in. It is worth noting that Windows Small Business Server 2011 has reached the end of its support lifecycle, so this CAL is primarily relevant for organizations maintaining legacy infrastructure while planning a migration path to current Microsoft server and cloud offerings.

Frequently Asked Questions

What does this CAL actually allow a device to do?

It licenses one device — such as a desktop, laptop, or terminal — to legally connect to and use services provided by a Windows Small Business Server 2011 Standard installation.

Is this a device CAL or a user CAL?

This is a device CAL, meaning the license is tied to a single device regardless of how many users operate that device.

Does this CAL include any server software?

No, this is only an access license. You must already have Windows Small Business Server 2011 Standard installed and licensed separately.

Can this CAL be transferred to a different device?

Microsoft's licensing terms generally allow reassignment of a device CAL to another device, but only after a waiting period and not on a short-term basis.
