FAQ: Microsoft Windows Server 2016 RDS 50 Device CAL

1. What exactly is Microsoft Windows Server 2016 RDS 50 Device CAL?

Microsoft Windows Server 2016 RDS 50 Device CAL is a package of 50 Device CAL access licenses for Remote Desktop Services in a Windows Server 2016 environment. This is not a program or physical installation software, but a license document that entitles a specified number of devices to legally use remote desktop features.

In practice, this means that if a company wants to enable work on a server via remote desktop, the Windows Server license alone is not sufficient. Additional RDS CAL permissions are required. In this variant, the license is assigned to devices, not to specific users. A package of 50 Device CALs will therefore be suitable where a specific pool of computers, terminals, or workstations use the server.

2. What does CAL mean and why is it needed separately?

The CAL abbreviation means Client Access License, or client access license. In the case of remote desktop services, we are talking about RDS CAL, which is an additional right to access remote services offered by the server.

This is a very important distinction: purchasing Windows Server does not automatically grant the right to use Remote Desktop Services for users or devices in a broader company scope. To work remotely legally, appropriate RDS CAL licenses are required. From a licensing compliance perspective, this is a document confirming access rights, not a medium, application, or installation key for a new system.

3. What is the difference between User CAL and Device CAL?

The difference concerns the way the license is assigned. User CAL is assigned to a specific user who can connect from different devices. Device CAL is assigned to a specific device, which can be used by multiple people.

The 50 Device CAL version will usually be a better choice when:

multiple employees work on the same computer in shifts,
the company uses terminals, kiosks, thin clients, or shared workstations,
the number of devices is stable and easy to count.

On the other hand, User CAL is more cost-effective when one employee logs in from a laptop, home computer, phone, and other devices. The choice of licensing model should result from the actual way of working in the organization.

4. How many RDS CAL licenses do I need in my company?

You should count how many devices will access remote desktop services. If the Device CAL model is chosen, each workstation, terminal, or other device connecting to the server should be covered by an appropriate license.

A package of 50 Device CALs means the right for a maximum of 50 devices. If the company has 38 workstations, such a package will cover the demand with a surplus. However, if 60 devices use the server, additional licenses must be purchased to maintain full compliance. In a license audit, the actual number of devices with access counts, not just the number of simultaneous connections.

5. Is this licence required if I already have Windows Server 2016?

Yes. Windows Server 2016 itself does not replace the RDS CAL licence. These are two different licensing elements. The server system provides the basis for the environment to operate, while access to remote desktop services for users or devices requires additional permissions.

In practice, a company using Remote Desktop Services should ensure it has:

a licence for the Windows Server,
basic Windows Server CAL access licences, if required in a given scenario,
RDS CAL licences for users or devices using the remote desktop.

Lack of proper licences may mean non-compliance with the manufacturer's terms, even if the technical environment is working correctly.

6. Is Microsoft Windows Server 2016 RDS 50 Device CAL a legal and full-fledged product?

Yes, provided it is purchased from a legitimate source. In the case of this type of product, the customer receives a full-fledged licence entitlement, not an "activator", unauthorised code, or unclear access account. This is particularly important, as we are talking about a licence, which is the legal basis for using the service.

When making a legitimate purchase, you should expect:

order confirmation,
product licence identification data,
a sales document,
the possibility of obtaining information about the licence origin.

Business customers rightly pay attention to this, as during an audit, it is not only the solution's operation that matters, but also the completeness of the documentation confirming its legality.

7. What does the delivery of such a licence look like, since it's not software?

Delivery is usually electronic. Since Microsoft Windows Server 2016 RDS 50 Device CAL is an access licence, the customer is not buying a box with a programme, but a licence entitlement along with the necessary data for implementation and commercial documentation.

This means that order fulfillment can be quick and convenient for the company. The customer receives the information needed to assign the licence in the server environment, as well as a document confirming the purchase. If assistance is needed before or after the purchase, you can contact us by phone at 00 800 121 1654.

8. Will I receive a VAT invoice when making a purchase?

Yes, when making a company purchase, a VAT invoice is the standard, which is an important element of accounting and licensing documentation. For many businesses, this has not only tax but also organisational significance, as the sales document is one of the basic proofs of legal licence acquisition.

It's worth storing the invoice along with the delivery confirmation and product information. For access licences, such documentation may be necessary during internal audits, IT resource inventory, and in the event of an external audit.

9. Can a Device CAL licence be transferred to another device or to another company?

The rule is to exercise caution when transferring licences. A Device CAL is assigned to a device, so it should not be treated as freely "wandering" between many stations from day to day. Changing the device may be acceptable in certain organisational situations, such as a permanent replacement of equipment, but it must comply with the licensing terms.

Even greater caution should be exercised when attempting to transfer the licence to another entity. The possibility of transfer depends on the type of licence, its source, and the terms of assignment. Therefore, before resale, assignment, or reorganisation of the company, it is worth confirming the rules for a specific case. If help is needed in assessing compliance, it is worth consulting the purchase by calling 00 800 121 1654.

10. How to maintain licence compliance when using RDS CAL?

The most important thing is to properly match the licensing model to the actual use and maintain full documentation. The company should know how many devices use RDS services, what type of CAL has been chosen, and whether the number of licences corresponds to the actual scale of use.

Good practices include:

keeping a record of devices with access to RDS,
storing VAT invoices and purchase confirmations,
using only legal licences from a trusted source,
periodic review of the number of CALs needed along with the growth of the company.

In the case of Microsoft Windows Server 2016 RDS 50 Device CAL, compliance means that a maximum of 50 devices have the right to access remote desktop services. If the infrastructure grows, the licences should be supplemented accordingly, so that the use of the solution is fully legal and secure from an audit point of view.
