For example, a CAL assigned to a user, allows only that user to access the server via any device. Likewise, if a DAL is assigned to particular device, then any authenticated user using that device is allowed to access the server. We can use a simple example to help highlight the practical differences between CAL and DAL licensing models and understand the most cost-effective approach: Assume an environment with Windows Server R2 standard edition and a total of 50 users and 25 devices workstations. In this case, we can purchase either 50 CAL licenses to cover the 50 users we have or alternatively 25 DAL licenses to cover the total amount of workstations that need to access the server. In this scenario, purchasing DALs is a more cost effective solution. If however we had 10 users with a total of 20 devices , e.
