How to Install the Remote Desktop Session Host Role
Applies to: Windows Server 2019, 2022 and 2025.
RD Session Host runs multi-user desktop and RemoteApp sessions. Role installation must be followed by a supported RDS deployment, licensing configuration, collection design and application testing.
RDS deployments require Windows Server licensing, the correct RDS CAL model and secure access design. Administrative RDP sessions are not a replacement. Review managed RDS hosting at networkmanager.info.
Prerequisites
- Join the server to the domain when using a standard RDS deployment.
- Confirm application support for multi-user Windows Server.
- Plan licensing, profiles and secure access.
- Take a backup and schedule restart.
