Remote Desktop Services (RDS): The Session Host Server Role

What is the Remote Desktop Session Host?

The Remote Desktop Session Host (RDSH) is a server role within Microsoft's Remote Desktop Services that hosts Windows applications or entire desktops to be accessed by remote users. This central component plays a crucial role in the deployment of virtualised applications and desktops, providing access to these resources via a network connection. Below, we explore the key benefits and operational considerations for implementing RDSH.

Benefits of RDSH

Scalability

RDSH servers are designed to handle numerous simultaneous connections, making them suitable for both small businesses and large enterprises. The ability to support a high number of users on a single RDSH server simplifies the IT infrastructure and reduces the administrative overhead.

Cost Efficiency

Centralising applications on RDSH servers allows organisations to extend the life of older hardware and reduce the costs associated with upgrades. Additionally, central management of applications can lower software licensing costs and IT support expenses.

Accessibility

RDSH enhances workplace flexibility by allowing users to access their applications and desktops from any location and any device with an internet connection, promoting productivity and supporting remote work policies.

Operational Considerations

Hardware Requirements

To effectively deploy RDSH, it is crucial to plan the server hardware specifications according to the expected load. This planning should consider CPU capabilities, RAM, and storage to ensure smooth operation and responsiveness of hosted applications and desktops.

Software Configuration

Installing the Windows Server operating system and enabling the RDSH role involves detailed configuration steps to optimise performance, security, and user access management. Proper setup of network settings, security policies, and session configurations are essential to leverage the full capabilities of RDSH.

By addressing these benefits and operational needs, IT professionals can ensure that their RDSH deployment enhances their organization's IT infrastructure while providing a scalable, cost-effective, and accessible solution for remote desktop access .

Implementing RDSH in Your IT Environment

Implementing the Remote Desktop Session Host (RDSH) requires a detailed approach to ensure that it integrates smoothly into an enterprise's IT infrastructure. Below, we outline the critical steps involved in setting up and configuring RDSH, publishing applications and desktops, and securing access.

Server Setup and Configuration

Initial Setup

Before deploying RDSH, it's essential to select and prepare the server hardware that meets the requirements for your expected workload. This includes adequate CPU power, RAM, and storage capacity to handle user sessions without performance degradation.

Operating System Installation

Install the Windows Server operating system on the server, ensuring it has the latest updates for security and stability.

Role Installation and Configuration

Enable the RDSH role via the Server Manager. This process involves adding the Remote Desktop Services role and configuring it to host applications and desktop sessions.

Application and Desktop Publishing

Publishing Applications

Identify the applications that need to be remotely accessible and configure them for remote access This involves setting permissions and ensuring that they are optimised for remote delivery.

Configuring Desktops

For environments where full desktop access is necessary, configure the desktop experience settings. This includes setting up themes, wallpapers, and other user interface options to ensure a consistent user experience across remote sessions.

Security and Access Control

User Authentication

Set up secure authentication mechanisms to verify the identities of users accessing the RDSH server. This can include traditional methods like Windows Authentication or more secure options such as two-factor authentication with smart cards.

Connection Security

Implement RD Gateway to manage and secure remote connections to the RDSH server from outside the network. The RD Gateway uses SSL encryption to protect the data integrity and confidentiality of remote sessions.

By following these detailed steps, organizations can ensure a robust and reliable RDSH deployment that provides high performance and secure access to remote applications and desktops.

Optimising RDSH for Better Performance

Effective optimization of the Remote Desktop Session Host (RDSH) is crucial to maximize both system efficiency and user satisfaction. This section explores strategic optimization techniques, focusing on load balancing, resource management, and session management to enhance the performance and reliability of the RDS environment.

Load Balancing with RD Connection Broker

Purpose of Load Balancing

Load balancing is essential to distribute user sessions and workloads evenly across multiple RDSH servers, preventing any single server from becoming overwhelmed. This balance helps maintain service continuity and optimises resource use.

Implementing with RD Connection Broker

RD Connection Broker manages the distribution of user sessions among available RDSH servers based on current load and server capacity. Configuring the RD Connection Broker involves setting connection rules and parameters that define how sessions are distributed, ensuring even load distribution and optimal resource utilisation.

Resource Management

CPU, Memory, and Storage Allocation

Appropriate allocation of resources is paramount in maintaining an efficient RDSH environment. Each server’s CPU, memory, and storage should be configured based on the specific needs of the applications it hosts and the number of users it supports.

Optimising Application Performance

Adjust resource allocation dynamically to meet changing demand and ensure high performance for critical applications, especially during peak usage times.

Session Management

Managing User Sessions

Implement policies that govern session timeouts and automatic reconnection. These policies help manage the load on the RDSH servers by freeing up resources occupied by inactive sessions and efficiently reconnecting users when they return.

Enhancing User Experience

Session management should aim not only to preserve system resources but also to provide a seamless user experience. Strategies include prioritising resources for active sessions and using session pre-launch techniques to reduce login times.

These optimization strategies are designed to enhance the overall performance of the RDSH environment, ensuring it meets the demands of modern enterprise applications and their users. By focusing on strategic resource allocation and efficient session management, IT administrators can significantly improve the responsiveness and reliability of their RDS deployments.
