What Is Remote Desktop Services (RDS)?
Managing software and security on every single employee's computer is a huge task. Remote Desktop Services (RDS) simplifies this by letting you run your apps and desktops on one powerful central server. Your team then connects to that server to do their work.
Whether you call it RDS or "Terminal Services," the goal is simple: your company's data and software stay safe in one place. Your team gets a smooth, fast experience whether they are working from a desktop in the office, a laptop at home, or a tablet while traveling.
Why Do I Need RDS CALs?
A common mistake is thinking that just having Windows Server is enough to let people work remotely. It actually isn't. While your server license runs the computer, Microsoft requires a Remote Desktop Services Client Access License (RDS CAL) for every person or device that connects to it through RDP.
Think of it like a ticket to enter a workspace. Without these "tickets" (CALs) installed on your system, users are only allowed a temporary 120-day trial. Once that trial ends, the server will stop allowing remote connections, locking your team out. Setting up your CALs early ensures your business stays up and running without any surprises.
Choosing the Right Type of License
User CAL
This license is tied to the person. If an employee uses multiple devices—like an office PC, a home laptop, and a tablet—they only need one User CAL. This is the best choice for remote and hybrid teams who work from different locations.
Device CAL
This license is tied to the computer. It’s perfect for businesses with shift workers, like call centers or hospitals. If three different people use the same physical computer during the day, you only need one Device CAL for that machine.
Version Compatibility & Future-Proofing
Microsoft has a simple rule for versions: your license must be the same year (or newer) as your server software. For example, a 2019 license won't work on a newer 2022 server.
The good news is that newer licenses have "Downgrade Rights." If you are using an older server now but plan to upgrade later, you can buy the newest 2025 licenses. They will work perfectly with your current older system and will also be ready to go when you eventually upgrade your server in the future.
