Device CAL For Windows Server 2019 RDS (Remote Desktop Services)

Buy a genuine Device CAL for Windows Server 2019 RDS license and cover shared devices for Remote Desktop Services on Windows Server 2019. The license key is delivered instantly by email and installed on your RD Licensing server, with no subscription to renew.

A Remote Desktop Services Device CAL (Client Access License) lets one physical device connect to session-based desktops and RemoteApp programs, however many people use it. It suits call centers, clinics, classrooms, factories and any workplace where staff share computers on shifts. It is the matching license for RDS farms that still run on Windows Server 2019. This page explains how the Device CAL for Windows Server 2019 RDS works, what else you need and how to install it.

Device CAL for Windows Server 2019 RDS: Quick Answer

Here is what you get with this license:

• Product: Windows Server 2019 Remote Desktop Services Device CAL
• Quantity: the CAL quantity shown on your order
• Coverage: each licensed device can be used by any number of people
• Installation: RD Licensing Manager on a Windows Server 2019 or later license server
• Compatibility: works with Windows Server 2019, 2016 and 2012 R2 RD Session Hosts
• License type: one-time purchase, no subscription
• Delivery: license key sent by email, typically instantly

If your session hosts run Windows Server 2019 and staff share computers, this is the license to buy.

Why Buy a Device CAL for Windows Server 2019 RDS?

Remote Desktop Services accepts connections without CALs only during a grace period of up to 120 days. After that, the RD Session Host refuses unlicensed devices, usually at the least convenient moment.

Common reasons to buy this license include:

• Licensing shared PCs on an existing Windows Server 2019 RDS farm
• Covering thin clients in production, retail or healthcare
• Adding devices as a team or site grows
• Running RemoteApp line-of-business software on shared terminals
• Ending a grace period before connections are refused

For a very small office, the Windows Server 2019 RDS 5-device pack may be simpler.

RDS Device CAL vs User CAL

Remote Desktop Services is licensed either per user or per device. Pick the model that matches how people actually work:

Question	Device CAL	User CAL
What is licensed	One physical device	One named person
Devices covered	One	Unlimited for that user
Users covered	Unlimited on that device	One
Best fit	Shared PCs, shifts and thin clients	Remote, hybrid and mobile staff
Tracking	Issued and tracked by the license server	Reported through Active Directory

Count the people and count the devices, then license whichever number is smaller. If the other model fits better, see the User CAL for Windows Server 2019 RDS.

What Else Does Remote Desktop Services Need?

The Device CAL for Windows Server 2019 RDS covers remote desktop access only. A properly licensed deployment also includes:

• A licensed Windows Server, such as Windows Server 2019 Standard
• A Windows Server CAL for each user or device that accesses the server
• An RDS CAL for each user or device that uses remote desktop sessions
• An RD Licensing server running Windows Server 2019 or later

Windows Server CALs and RDS CALs are separate licenses. Microsoft’s RDS client access license documentation explains the rules in detail.

Device CAL for Windows Server 2019 RDS Compatibility

RDS CALs cover their own Windows Server version and earlier ones. The Device CAL for Windows Server 2019 RDS therefore works with devices on Windows Server 2019, 2016 and 2012 R2 RD Session Hosts.

The license server must run the same version as the CALs or a newer one, so these CALs install on Windows Server 2019 or later. Devices connecting to Windows Server 2022 or 2025 session hosts need CALs of that version, such as the Device CAL for Windows Server 2022 RDS.

Upgrading an RDS Farm from Windows Server 2019

If you plan to move session hosts to a newer Windows Server later, the order of work matters. The Device CAL for Windows Server 2019 RDS keeps today’s farm licensed while you prepare.

A sensible sequence looks like this:

• Upgrade or rebuild the RD Licensing server first
• Install CALs for the new version alongside the existing 2019 CALs
• Move session hosts to the new version one at a time
• Retire the 2019 CALs once no 2019 hosts remain

Tackled in that order, an RDS upgrade becomes less of a maze and more of a checklist.

How Many Device CALs Do You Need?

Count every physical device that opens a remote desktop or RemoteApp session, including thin clients, shared PCs and kiosks. The number of people using each device does not matter.

Some quick examples:

• A reception area with 4 shared PCs
• A production floor with 12 thin clients
• A school lab with 30 shared computers

The license server issues a Device CAL the first time each device connects, so replacing hardware often can use CALs faster than expected.

Who Should Buy the Device CAL for Windows Server 2019 RDS?

This license is the right choice when you:

• Run RD Session Hosts on Windows Server 2019, 2016 or 2012 R2
• Have more people than devices using remote desktops
• Run shift work on shared computers or thin clients
• Want licenses that the server tracks automatically
• Prefer a one-time purchase instead of a subscription

How to Install the Device CAL for Windows Server 2019 RDS

RDS CALs are installed on the RD Licensing server, not on each client device:

1. Install the Remote Desktop Licensing role on a server running Windows Server 2019 or later.
2. Open RD Licensing Manager, right-click the server and select Activate Server.
3. Right-click the server again and select Install Licenses.
4. Choose the license program shown in your Bcdkey delivery email.
5. Enter the license key, select Windows Server 2019 and the Per Device CAL type, and enter the quantity.
6. Finish the wizard and confirm the licenses appear in RD Licensing Manager.

Next, set the licensing mode to Per Device. In Server Manager, open Remote Desktop Services > Overview > Tasks > Edit Deployment Properties > RD Licensing. Servers outside a deployment use this Group Policy path:

Computer Configuration > Administrative Templates > Windows Components > Remote Desktop Services > Remote Desktop Session Host > Licensing

A licensing mode that does not match the installed CALs is the most common cause of lingering grace period warnings.

Delivery, Order Tracking and Support

Your license key is sent by email, typically instantly after payment, and is also saved in My Account. You can follow any order with Track Order.

If installation does not complete, open a support ticket with a screenshot of the RD Licensing Manager message. More licenses are listed in our RDS CALs and Windows Server 2019 categories. Need a larger quantity? The Bcdkey B2B wholesale program handles volume orders.
