Remote Desktop Services (RDS) in Windows Server environments serves the purpose of enabling users to remotely access desktops, applications, and data hosted on a centralized server. It provides a platform for delivering virtual desktop infrastructure (VDI) and RemoteApp programs to users across a network, allowing for centralized management, increased security, and improved accessibility.

  1. Remote Desktop Session Host (RDSH):
    • Formerly known as Terminal Services, RDSH allows multiple users to access desktop sessions simultaneously on a server. Each user's session is isolated from others, providing a personalized desktop experience.
    • RDSH hosts the user's session environment, including applications and data, while the client device (such as a PC or thin client) displays the remote desktop interface.
  2. Remote Desktop Virtualization Host (RDVH):
    • RDVH enables the deployment of virtual desktops using Hyper-V virtualization technology. It hosts multiple virtual machines (VMs), each running a separate instance of a desktop OS, such as Windows 10 or Windows 11.
    • Users connect to these virtual desktops using Remote Desktop Protocol (RDP) from their client devices, providing a full desktop experience similar to accessing a physical desktop.
  3. Remote Desktop Gateway (RD Gateway):
    • RD Gateway acts as a secure entry point for remote users to access RDS resources from outside the corporate network. It establishes encrypted RDP connections over HTTPS, providing secure remote access without the need for a VPN.
    • RD Gateway performs endpoint authentication and authorization, ensuring that only authorized users and devices can connect to RDS resources.
  4. Remote Desktop Connection Broker (RDCB):
    • RDCB is responsible for brokering connections between remote users and virtual desktops or session-based desktops. It maintains information about available resources and user sessions, directing incoming connection requests to the appropriate host.
    • RDCB provides load balancing and session reconnection capabilities, optimizing resource utilization and ensuring high availability for users.
  5. Remote Desktop Web Access (RD Web Access):
    • RD Web Access provides a web-based portal for users to discover and launch RemoteApp programs and virtual desktops from a web browser. It presents users with a customizable interface listing available resources, simplifying access to RDS applications and desktops.
    • Users can access RD Web Access from any device with a compatible web browser, making it convenient for remote and mobile users to connect to RDS resources.
