Remote Desktop Services User CALs for Windows Server 2019 as used software

Users need a Client Access License (CAL) to use Windows Server Remote Desktop Services, which allows them to access Windows programs on a corporate network, including files, from anywhere. One option is the User CAL for RDS, which makes it available to a specific user as part of a remote desktop session. The RDS User CALs from Wiresoft offer a low-priced alternative to conventional license providers, as they are used software that offers the same functionality.

What are the benefits of Windows RDS CALs 2019?

Remote Desktop Services (RDS) are technically a specific server role in Windows Server 2019, formerly known as Terminal Services. RDSs allow authorized users to access Windows programs on the corresponding Windows server via a host in the form of a remote desktop session. Users with a corresponding access license (User CAL) can access them either locally via a company network or remotely via the Internet.

For administrators, Windows Remote Desktop Services provide an efficient way to deploy and manage software in a corporate environment, including authorized users. Software programs do not have to be installed on each end device because they are easily deployed to a central location - the server. This makes them easier to control and update. The effort for maintenance and provision of workstations is thus significantly reduced.

The advantages of Remote Desktop CALs for users

Users, on the other hand, benefit from a standardized Windows working environment with an RDS CAL, which is particularly evident with a User CAL in that every end device has a uniform desktop including data - regardless of whether they are at the company location, on the road, at a customer site or in the home office. In addition, with Remote Desktop Services they benefit from the performance of the server even if the end device they are using has weaker hardware. When using Hyper-V, they can also use a virtual computer.

When a user with a User CAL accesses a specific program during a remote desktop session with the host, the program is executed on the server. Each user has specific rights and only sees their own session, regardless of other client connections.

Version Compatibility for Remote Desktop Services CALs for Windows Server

The User CAL for an access-authorized employee (resp Device CAL) must be compatible with the Windows Server version in order to connect to it for a session. A 2019 RDS User CAL can therefore access either Windows Server 2019, or an older server version (downgrade) - but not any future higher server versions.

Windows Server 2019 Remote Desktop Services Overview

Specifically, the RDS for Windows Server 2019 are made up of the following components, which allow a user with a client access license to use apps and services through them:

Remote Desktop Session Host

The Remote Desktop Session Host - also known as RD Session Host - contains all desktops or apps that are provided session-based to a user with a CAL. They can access them through a remote desktop client or a web client.

Remote Desktop Connection Broker

The Remote Desktop or RD Connection Broker manages all Remote Desktop connections - both to desktops and remote apps. If a connection is lost during a session, the RD connection broker re-establishes it with the correct RD session host server.

Remote Desktop Gateway

Through the Remote Desktop Gateway, a user with their User CAL on a public network accesses a Windows desktop or those applications hosted by Microsoft Azure Cloud Services.

Web Access for RD

Web Access for Remote Desktop provides access to desktops or applications through a web portal by launching the Microsoft Remote Desktop client application on the endpoint device. Web Access for RD also provides the ability to publish desktops or apps only to specific users or groups.

Remote Desktop Licensing

RD licensing governs license usage when deploying Remote Desktop Services. Depending on whether a user or endpoint connects to the remote desktop license server, a specific RDS CAL is made available and a connection is created between the RD session host server and the desktops or apps in use to do so.

Comparison of User CALs vs. Device CALs for Remote Desktop Services to Windows Server 2019

The licensing system for using a server from Microsoft is based on Client Access Licenses, abbreviated as CALs. Therefore, the deployment of a server software is done with a corresponding access license regardless of its usage. Remote Desktop Services CALs ensure that only authorized users have access to the server, which in addition to the differentiated access management per user via the server administration also means additional security, since foreign users have no access to services or data.

Microsoft provides for Remote Desktop Services 2019 it two different types of CALs:

  • User CALs, when the user is granted access rights, and
  • Device CALs, when the endpoint device (PC, Laptop, Table, Mobile) is the focus.

Special features of the User CAL for Remote Desktop Services 2019

A User CAL is in principle exclusively intended for a single dedicated user and registered in his name. The User CAL then grants that user the right to access a server for the host during Remote Desktop sessions from an unlimited number of client computers or other devices, but only one at a time. By freely choosing the end device, the user can therefore switch between desktop PC in the company, mobile phone or tablet etc. on the road and end device in the home office and thus use his registered account via the Windows server.

The RDS CALs per user are not enforced by Remote Desktop Licensing. This means that client connections are made regardless of the number of Remote Desktop Services User CALs installed on the license server. However, there must be a valid User CAL for each user. Therefore, the exact number of User CALs in use in a company must be recorded and accordingly enough access licenses must be installed on the server so that each user is provided with a CAL from this pool. This is the task of the Remote Desktop Licensing Manager.

Overview of all features of User CALs for RDS

  • User CALs are assigned to a specific user in Active Directory - not to a device
  • User RDS CALs are not temporarily available and cannot be revoked
  • Each User CAL is tracked by the license server
  • However, they cannot be tracked within a team
  • The number of defined User CALs can also be overloaded - contrary to the Remote Desktop license agreement


Which type of Remote Desktops Services CALs offers more benefits in an organization varies on a case-by-case basis. Therefore, the decision for a certain form of client access licensing depends on the number of employees on the one hand and on their preferred way of working on the other hand: For employees who flexibly access Windows Server on different devices and workstations - internal and external as well as mobile - e.g. also on the train or in the home office or on the road, an RDS User CAL is the better choice.
