Remote Desktop Services client access licenses (RDS CALs) were formerly sold in packs of 5 and 20. Customers buying Retail RDS CALs didn’t have a choice of buying a single CAL, which meant that they had to buy the next higher CAL Pack. For example, if the customer wanted 6 CALs, he had to buy two 5-CAL Packs.
In response to customer requests, we now offer Single CAL Packs, giving customers the ability to buy exactly the number of CALs that they need. Single CAL Packs are available for Windows Server 2008 and Windows Server 2008 R2 in the following two types:
Single CAL Packs are available with Retail and OEM channels and not with Volume licensing channels like Select, Open and Enterprise Agreements, as they can already order in units of one. 5- and 20-CAL packs are also still available.
To install a Single CAL Pack on Windows Server 2008 R2 license server, follow the steps you would use to install any other retail CAL Pack. For Windows Server 2008, ask your TAM (Technical Account Manager) or EE (Escalation Engineer) for
and install it on the license server. After installing this QFE on Windows Server 2008 license server, you can follow the same procedure to install the Single CAL Pack as any other retail CAL Pack.
