FAQ – Windows Server 2025 Remote Desktop Services (RDS) CALs

How do I activate Windows Server 2025 RDS CAL licenses?

Quick Answer: Use RD Licensing Manager to activate and install CALs via the Microsoft Clearinghouse (online or phone).
Steps to Activate:

1. Install the RD Licensing Role:
   In Server Manager, add the Remote Desktop Licensing role on your Windows Server 2025 instance.

2. Open RD Licensing Manager:
   Go to Tools > Remote Desktop Services > Remote Desktop Licensing Manager.

3. Activate the License Server:
   Right-click the server name > Activate Server > choose automatic (internet) or manual (phone).

4. Install License Keys:
   After activation, right-click again and choose Install Licenses, then enter your RDS CAL key.

5. Verify Installation:
   The installed licenses will show up under the “Installed Licenses” section in RD Licensing Manager.

What is the difference between User CAL and Device CAL for RDS?

Short Answer:

• User CALs license individual people to access RDS from any device.

• Device CALs license specific devices, allowing any number of users to connect from those devices.

Comparison Table:

How many users can connect simultaneously with 50 RDS CALs?

Direct Answer:

• With 50 User CALs, up to 50 named users can connect from unlimited devices.

• With 50 Device CALs, an unlimited number of users can connect from exactly 50 licensed devices.

Important Notes:

• CALs don’t limit “concurrent sessions” directly—they govern who is licensed to connect, not how many sessions run simultaneously.

• The actual number of simultaneous connections also depends on your server’s hardware (CPU, RAM) and configuration.

Can I use Windows Server 2025 RDS CALs with older server versions?

Quick Answer: No. RDS CALs are not backward compatible.

Compatibility Rules:

• RDS CALs must match or exceed the server version.
  → Example: Windows Server 2025 CALs work only with Server 2025.

• You cannot use 2025 CALs with 2019 or 2022 servers.

• If you’re upgrading your server OS, you must also upgrade your CALs.

What happens if I exceed my RDS CAL license limit?

Short Answer:
RDS will eventually deny unlicensed connections and may display errors like:

“The remote session was disconnected because the license store creation failed.”

Recommended Actions:

• Monitor CAL usage in RD Licensing Manager regularly.

• Add more CALs if approaching or exceeding limits.

• Set session timeouts, idle disconnect policies, and reconnect settings to optimize usage.

• Use RDS Connection Broker and load balancing across multiple hosts if demand is high.
