FAQ: Microsoft Windows Server 2019 RDS 50 Device CAL
1. What exactly is Microsoft Windows Server 2019 RDS 50 Device CAL?
Microsoft Windows Server 2019 RDS 50 Device CAL is a package of 50 Device CAL licenses for Remote Desktop Services in a Windows Server 2019 environment. It is not a program or a separate operating system, but a license document that authorizes devices to legally use remote desktop services.
In practice, this means that if a company wants to provide employees or workstations with access to remote desktop, published applications on the server, or terminal work, the Windows Server license alone is not enough. Additional RDS CAL permissions are required. In this variant, the right of access is assigned to devices, not to specific individuals.
2. What does the CAL abbreviation mean and why is this license required?
CAL stands for Client Access License, which is a client access license. In the case of RDS, we are talking about RDS CAL, which is a license required when users or devices connect to the server using remote desktop services.
It is essential to distinguish between these: purchasing Windows Server does not automatically grant the right to use remote desktop features for any number of workstations. To comply with Microsoft's licensing rules, you must have:
- a license for the server itself,
- appropriate Windows Server CAL licenses if required in a given scenario,
- and additionally RDS CAL for access through Remote Desktop Services.
RDS CAL is therefore an element of license compliance, not a functional add-on installed as a user application.
3. What is the difference between User CAL and Device CAL?
This is one of the most frequently asked questions and also the most important decision when making a purchase.
User CAL is assigned to a specific user. One person can then connect from multiple devices, such as a desktop computer, laptop, and home terminal.
Device CAL is assigned to a specific device. Multiple people can use one computer, terminal, or workstation, but the license still applies to that one device.
The 50 Device CAL variant is most often chosen by companies that have:
- shared workstations,
- shift work,
- warehouse, reception, or production terminals,
- environments where multiple employees use one device.
If, on the other hand, one employee uses multiple devices, the User CAL model is usually more beneficial.
4. How many RDS Device CAL licenses do I need?
The number of licenses is determined by the number of devices that will access RDS services. If 50 different devices are to connect to the server, a package covering exactly 50 Device CALs is required.
The number of simultaneous connections is not relevant, only the number of devices authorized to access. This is crucial for compliance. Even if only a portion of the workstations are active on a given day, each device with the right to connect should be covered by the appropriate license.
Example: a company has 38 terminals and 12 reception computers using remote desktop. This gives a total of 50 devices, and exactly that many Device CAL licenses should be possessed.
5. Is this license a physical product or software to download?
No. This is a CAL/RDS license, which is a legal entitlement, not a classic software application. The customer is not buying a new user application but a document confirming the right to use remote desktop services in accordance with Microsoft's terms.
Therefore, the product should be understood as a component of IT environment legalization. Delivery usually includes licensing data, purchase confirmation, and commercial documents. This is particularly important for IT departments, accounting, and auditing, as the purpose of the purchase is to ensure license compliance, not to install a "program" in the traditional sense.
6. Are the key or license legal and how can their authenticity be verified?
The legality of the license is fundamental. When making a purchase, one should expect a fully legitimate, legal license from an authorized sales channel, along with a set of documents confirming the transaction.
In practice, the customer should pay attention to:
- the consistency of the product name with the license actually being purchased,
- receiving a sales document,
- the ability to demonstrate the origin of the license during an audit or inspection,
- clear conditions regarding the type of license: in this case, RDS Device CAL, not a full server license.
For companies, it is also important that the purchase is documented with a VAT invoice, which facilitates both accounting settlement and demonstration of legality in internal documentation.
7. What does the delivery look like and what documents do I receive after purchase?
In the case of licenses of this type, delivery usually has an electronic character. This means quick execution without the need to wait for a physical medium. The customer receives the information necessary to handle the order and documents confirming the acquisition of the license.
Standardly, the following are important:
- order confirmation,
- license data,
- VAT invoice,
- commercial documentation useful for evidence and archiving.
If it is necessary to clarify the license variant or the User/Device model before purchase, it is worth consulting before finalizing the order. For sales and informational matters, you can contact us by phone at 00 800 121 1654.
8. Can the Device CAL license be transferred to another device?
The rule is that Device CAL is assigned to a specific device. It should not be treated as a license that can be freely "moved" between multiple computers depending on daily needs. This fixed assignment decides on the compliance of the Device model.
Transfer can only be considered in situations consistent with licensing conditions, such as permanent equipment replacement, device decommissioning, or infrastructure changes. However, this should not serve to circumvent the obligation to purchase the appropriate number of licenses.
If a company frequently rotates equipment or employees use multiple devices, it is worth evaluating earlier whether the User CAL model would not be safer and more organizationally straightforward.
9. What are the consequences for a company if it uses RDS without proper CALs?
The lack of proper licenses means the risk of non-compliance. In practice, this can lead to problems during audits, the need to supplement licensing gaps, and additional costs and formal complications.
For enterprises, it is crucial not only that the environment works technically but also that it is used in accordance with the manufacturer's conditions. Therefore, purchasing the appropriate number of RDS CALs should be treated as an element of compliance policy, just as important as the legality of the operating system or office packages.
The safest approach is simple: count the actual number of devices or users, select the appropriate licensing model, and keep a complete set of purchase documents.
10. How do I know whether to choose 50 Device CAL or User CAL?
It is best to base the decision on the company's work style. Device CAL usually pays off where multiple people use one computer, such as in production, service points, warehouses, schools, or shift work. User CAL works better when one employee uses multiple devices.
If the organization has exactly 50 shared workstations and these devices are a permanent part of the infrastructure, the Microsoft Windows Server 2019 RDS 50 Device CAL variant is a logical choice. However, if the environment is mobile and users work from multiple locations, it is worth analyzing the per-user model.
In case of doubts before purchase, it is worth consulting the usage scenario to select a license that complies with the actual work style and avoid both under-licensing and unnecessary costs. Sales information can be obtained by calling 00 800 121 1654 or by contacting [email protected].
