remote desktop services architecture

The Remote Desktop Connection 6.1 client is comprised of the following four functional layers containing individual objects that interact through a common set of core components. The channels connect to the client over the TCP connection; as the channels are accessed for data, the client is informed of the request, which is then transferred over the TCP connection to the application. [22], Windows 7 includes built-in support for RemoteApp publishing, but it has to be enabled manually in registry, since there is no RemoteApp management console in client versions of Microsoft Windows. Windows Desktop Sharing API exposes two objects: RDPSession for the sharing session and RDPViewer for the viewer. It handles the job of authenticating clients, as well as making the applications available remotely. This is also available for iOS and Android. Remote Desktop Session Host (RDSH) is a role in Remote Desktop Services . publish Remote Desktop with Azure AD Application Proxy, Basic deployment – This contains the minimum number of servers to create a fully effective RDS environment, Highly available deployment – This contains all necessary components to have the highest guaranteed uptime for your RDS environment. This Quick Start deploys Remote Desktop Gateway (RD Gateway) on the AWS Cloud. Microsoft produces an official client for a variety of non Windows platforms: There have been numerous non-Microsoft implementations of clients that implement subsets of the Microsoft functionality for a range of platforms. Remote Desktop Services has two standard architectures: Basic deployment – This contains the minimum number of servers to create a fully effective RDS environment Highly available deployment – This contains all necessary components to have the highest guaranteed uptime for your RDS environment We will begin by discussing about RDS core components, when to use one server and when multi-server deployment and we will install RDS on WIndows Server 2016. [4] Later versions of the protocol also support rendering the UI in full 32-bit color, as well as resource redirection for printers, COM ports, disk drives, mice and keyboards. [2][4] Moreover, a remote session can also span multiple monitors at the client system, independent of the multi-monitor settings at the server. In late December 2004 the two companies announced a five-year renewal of this arrangement to cover Windows Vista. You signed in with another tab or window. It allows a user to remotely log into a networked computer running the terminal services server. [11], The key server component of RDS is Terminal Server (termdd.sys), which listens on TCP port 3389. It also creates the other virtual channels and sets up the redirection. If you arrive to the conclusion that your Thinfinity® Remote Desktop Server environment would benefit from using load balancing, you can choose between two possible architectures. Download this app from Microsoft Store for Windows 10, Windows 8.1, Windows 10 Mobile, Windows Phone 8.1, Windows 10 Team (Surface Hub), HoloLens. It is, however, not available in client versions of Windows OS, where the server is pre-configured to allow only one session and enforce the rights of the user account on the remote session, without any customization.[2]. User interfacesare displayed from … When creating the new session, the graphics and keyboard/mouse device drivers are replaced with RDP-specific drivers: RdpDD.sys and RdpWD.sys. However, if you don't have a traditional AD and only have an Azure AD tenant—through services like Office365—but still want to leverage RDS, you can use Azure AD Domain Services to create a fully managed domain in your Azure IaaS environment that uses the same users that exist in your Azure AD tenant. With resource redirection, remote applications can use the resources of the local computer. The remote session information is stored in specialized directories, called Session Directory which is stored at the server. RD Gateway uses the Remote Desktop Protocol (RDP) over HTTPS to establish a secure, encrypted connection between remote users and EC2 instances running Microsoft Windows, without needing to configure a virtual private network (VPN). [27] A viewer must authenticate itself before it can connect to a sharing session. Cannot retrieve contributors at this time. The Terminal Server respects the configured software restriction policies, so as to restrict the availability of certain software to only a certain group of users. Below are various configurations for deploying Remote Desktop Services to host Windows apps and desktops for end-users. These executables are loaded in a new session, rather than the console session. It will invoke the Remote Desktop Connection client, which will connect to the server and render the UI. [25] Windows Desktop Sharing can be used to share the entire desktop, a specific region, or a particular application. Use Windows Server 2019 for your Remote Desktop infrastructure (the Web Access, Gateway, Connection Broker, and license server). Per-application filters capture the application Windows and package them as Window objects. Use this Quick Start to deploy a highly available Remote Desktop Gateway (RD Gateway) architecture on the AWS Cloud, automated by AWS CloudFormation. With low encryption, user input (outgoing data) is encrypted using a weak (40-bit RC4) cipher. [2] In addition to regular username/password for authorizing for the remote session, RDC also supports using smart cards for authorization. RDS is Microsoft's implementation of thin client architecture, where Windows software, and the entire desktop of the computer running RDS, are made accessible to any remote client machine that supports Remote Desktop Protocol (RDP). Remote Desktop Services Architecture Remote Desktop Services provides a virtualization platform for accelerating and extending desktop and application deployments from the data center to any device. [12] RDP communications are encrypted using 128-bit RC4 encryption. ", https://en.wikipedia.org/w/index.php?title=Remote_Desktop_Services&oldid=1008086028, Creative Commons Attribution-ShareAlike License, To alternate between the full screen and window mode of remote desktop, you can use, This page was last edited on 21 February 2021, at 13:58. Terminal Services Web Access (TS Web Access) makes a RemoteApp session invocable from the web browser. [25][27], Windows Desktop Sharing API is used by Windows Meeting Space and Windows Remote Assistance for providing application sharing functionality among network peers.[26]. Remote Desktop Services (RDS), known as Terminal Services in Windows Server 2008 and earlier,[1] is one of the components of Microsoft Windows that allow a user to take control of a remote computer or virtual machine over a network connection. A RemoteApp can also be registered as handler for file types or URIs. It can also be configured by using Group Policy or Windows Management Instrumentation. Have an existing Remote Desktop deployment built on a previous version of Windows Server? tagged Dan Stolts / IT Manager / Poster / resources / Virtualization / Windows 7 / Windows Server 2008 R2 . A viewer can either be a passive viewer, who is just able to watch the application like a screencast, or an interactive viewer, who is able to interact in real time with the remote application. [2], Once a client initiates a connection and is informed of a successful invocation of the terminal services stack at the server, it loads up the device as well as the keyboard/mouse drivers. When sharing applications individually (rather than the entire desktop), the windows are managed (whether they are minimized or maximized) independently at the server and the client side. [2] With RDC 6.0, the resolution of a remote session can be set independently of the settings at the remote computer. [22] Multiple applications can be started in a single RemoteApp session, each with their own windows. [18][19], RemoteApp (or TS RemoteApp) is a special mode of RDS, available in Windows Server 2008 R2 and later, where remote session configuration is integrated into the client operating system. With version 6.0, if the Desktop Experience component is plugged into the remote server, remote application user interface elements (e.g., application windows borders, Maximize, Minimize, and Close buttons etc.) The RemoteApp can also be packaged in a Windows Installer database, installing which can register the RemoteApp in the Start menu as well as create shortcuts to launch it. The Azure AD Application Proxy PaaS role fits nicely with this scenario. [2], In Windows Server 2008, it has been significantly overhauled. [8][9] Third-party developers have also created client software for RDS. See screenshots, read the latest customer reviews, and compare ratings for Microsoft Remote Desktop. [15] This also allows the option to use Internet Explorer as the RDP client. The two standard architecture diagrams above use the RD Web/Gateway servers as the Internet-facing entry point into the RDS system. The two standard architecture diagrams above are based on a traditional Active Directory (AD) deployed on a Windows Server VM. Applies to: Windows Server (Semi-Annual Channel), Windows Server 2019, Windows Server 2016. This feature was introduced in the Windows Server 2008 and Windows Home Server products. Fast User Switching is part of Winlogon and uses RDS to accomplish its switching feature. It explains the functions and roles of Remote Desktop Session Host, Remote Desktop Virtualization Host, Remote Desktop Connection Broker, Remote Desktop Web Access, Remote Desktop Gateway, Remote Desktop Licensing, and RemoteFX. [4] Terminal Services were then renamed to Remote Desktop Services with Windows Server 2008 R2[5] in 2009. [13], Terminal Server is the server component of Terminal services. It provides an extensible platform for a Virtual Desktop Infrastructure. Remote Desktop Services (RDS) Component Architecture Poster Windows Server 2008 R2. [26] Windows Desktop Sharing can also be used to share multi-monitor desktops. Today we’re continuing on with Remote Desktop Services with a look at the architecture. For example, rdesktop supports Unix platforms. [23], A RemoteApp can be packaged either as a .rdp file or distributed via an .msi Windows Installer package. Unlike Terminal Services, which creates a new user session for every RDP connection, Windows Desktop Sharing can host the remote session in the context of the currently logged in user without creating a new session, and make the Desktop, or a subset of it, available over RDP. Here we go: There have been some design changes in RDS (remote desktop services) and in RDC (remote desktop client). The excitement is definitely building. Let’s start by discussing the legacy RDP. Users can access this through a web client on a supported browser or through a Remote Desktop client, which runs on Windows, macOS, iOS and Android devices. This poster provides a visual reference for understanding key Remote Desktop Services technologies in Windows Server 2008 R2. Azure AD Domain Services can work in either deployment: basic or highly available. [4], Terminal Server is managed by the Terminal Server Manager Microsoft Management Console snap-in. This poster provides a visual reference for understanding key Remote Desktop Services technologies in Windows Server 2008 R2. RDS was first released as Terminal Server in Windows NT 4.0 Terminal Server Edition, a stand-alone edition of Windows NT 4.0 which included Service Pack 3 and fixes. T hinfinity ... Thinfinity® Remote Desktop Server is a secure, high-performance HTTP / WebSockets server, which serves the web pages needed to run the Thinfinity® Remote Desktop Web Client on the web browser. Windows Server 2003 onwards, it can use a FIPS 140 compliant encryption schemes. This removes the complexity of manually syncing users and managing more virtual machines. The official MS RDP client for macOS supports RD Gateway as of version 8. It is also entrusted with the job of restricting the clients according to the level of access they have. The task of establishing the remote session, as well as redirecting local resources to the remote application, is transparent to the end user. Opening a file registered with RemoteApp will first invoke Remote Desktop Connection, which will connect to the terminal server and then open the file. For some environments, administrators would prefer to remove their own servers from the perimeter and instead use technologies that also provide additional security through reverse proxy technologies. The best practice when deploying an RDS solution is to have each component hosted on their own dedicated servers. This entire procedure is done by the terminal server and the client, with the RDP mediating the correct transfer, and is entirely transparent to the applications. Such centralization can make maintenance and troubleshooting easier. Remote Desktop Connection (RDC, also called Remote Desktop, formerly Microsoft Terminal Services Client, mstsc or tsclient)[28][29] is the client application for RDS. See Remote Desktop Services architecture for a detailed discussion of the different pieces that work together to make up your Remote Desktop Services deployment. with is referred to as a Remote Desktop Session Host (RD Session Host), which connects the RDP client to the remote application. RDP communication can be encrypted; using either low, medium or high encryption. It explains the functions and roles of Remote Desktop Session Host, Remote Desktop Virtualization Host, Remote Desktop Connection Broker, Remote Desktop Web Access, Remote Desktop Gateway, Remote Desktop Licensing, and RemoteFX. The Remote Desktop Services team have created a poster to help you plan, build, and run your RDS environment. RemoteFX was added to RDS as part of Windows Server 2008 R2 Service Pack 1. Windows XP Home Edition does not accept any RDC connections at all, reserving RDS for Fast User Switching and Remote Assistance only. [!NOTE] The function layers that make up RDC Architecture are: The RdpDD.sys is the device driver and it captures the UI rendering calls into a format that is transmittable over RDP. Remote Desktop Services has two standard architectures: Though the standard RDS deployment architectures fit most scenarios, Azure continues to invest in first-party PaaS solutions that drive customer value. It includes the TS Web Access Web Part control which maintains the list of RemoteApps deployed on the server and keeps the list up to date. [16][17] The web client uses the TLS secured port 443 and does not use the RD Gateway to transport traffic, instead relying solely on the remote desktop session host aspect of remote desktop services. Server Roles in RDS: There are three core roles to setup a RDS environment and are as follows: Remote Desktop Session Host [RDSH]: Applications are installed and published from the Session Host servers. When a Remote Desktop Protocol (RDP) client connects to this port, it is tagged with a unique SessionID and associated with a freshly spawned console session (Session 0, keyboard, mouse and character mode UI only). [14] This increases the security of RDS by encapsulating the session with Transport Layer Security (TLS). Remote Desktop clients enable access from any Windows, Apple, or Android computer, tablet, or phone. Remote Desktop Services in Windows Server. [25] The RDPSession object contains all the shared applications, represented as Application objects, each with Window objects representing their on-screen windows. Although RDS is shipped with most editions of all versions of Windows NT since Windows 2000,[3] its functionality differs in each version. The most common are: "Windows Remote Desktop Services spotlight", "Technical Overview of Terminal Services in Windows Server 2003", "Whats new in Terminal Services in Windows Server 2008", "4: Remote Desktop Services and VDI: Centralizing Desktop and Application Management", "How to change the listening port for Remote Desktop", "Frequently Asked Questions about Remote Desktop", "Citrix and Microsoft Sign Technology Collaboration and Licensing Agreement", "Connection Configuration in Terminal Server", "Microsoft Has Released the HTML5-Based RDP Web Client", "Remote Desktop HTML5 client on Windows Server 2019", "RD Web Client (HTML5) – New Features In 1.0.11", "The Microsoft Platform: HTML5 client for Microsoft Remote Desktop Services 2016: Remote Desktop Web Client", "Description of the Remote Desktop Connection 6.1 client update for Terminal Services in Windows XP Service Pack 2", "Terminal Services RemoteApp (TS RemoteApp)", "Terminal Services RemoteApp Session Termination Logic", "How to enable RemoteApp (via RDP 7.0) within VirtualBox or VMWare running Windows 7, Vista SP1+ or Windows XP SP3", "Why doesn't the New Folder command work in the root of a redirected drive resource in a Remote Desktop session? These diagrams are primarily intended to illustrate how the RDS roles are colocated and use other services. Terminal Server can also integrate with Windows System Resource Manager to throttle resource usage of remote applications. This poster provides a visual reference for understanding key Remote Desktop Services technologies in Windows Server 2008 R2. User interfaces are displayed from the server onto the client system and input from the client system is transmitted to the server - where software execution takes place. Architecture: Top Previous Next . so as to make the applications more responsive. The RD Gateway component uses Secure Sockets Layer (SSL) to encrypt the communications channel between clients and the server. For an organization, RDS allows the IT department to install applications on a central server instead of multiple computers. In this arrangement, Citrix has access to key source code for the Windows platform, enabling its developers to improve the security and performance of the Terminal Services platform. RDSH can host Windows session-based applications and desktops that can be shared with users remotely. This article defines a set of architectural blocks for using Remote Desktop Services (RDS) and Microsoft Azure virtual machines to create multitenant, hosted Windows desktop and application services, which we call "desktop hosting." Remote Desktop Gateway (RD Gateway) grants users on public networks access to Windows desktops and applications hosted in Microsoft Azure's cloud services. Remote Desktop Services (RDS), known as Terminal Services in Windows Server 2008 and earlier, is one of the components of Microsoft Windows that allow a user to take control of a remote computer or virtual machine over a network connection. Windows Server allows two users to connect at the same time. However, you can deploy Remote Desktop Services on-premises and on other clouds. RDC presents the desktop interface (or application GUI) of the remote system, as if it were accessed locally. It also allows creation of virtual channels, which allow other devices, such as disc, audio, printers, and COM ports to be redirected, i.e., the channels act as replacement for these devices. Check out this poster for a visual representation and definition of how Microsoft Remote Desktop Services … To support user interaction with remote applications and resources, Remote Desktop Services protocols transport input from the user (such as from the keyboard or mouse) to the server. RDS is Microsoft's implementation of thin client architecture, where Windows software, and the entire desktop of the computer running RDS, are made accessible to any remote client machine that supports Remote Desktop Protocol (RDP). Applies to: Windows Server (Semi-Annual Channel), Windows Server 2019, Windows Server 2016. You can get a copy of the poster by right-clicking the image and saving it to your local system. In the guide there's an important note that Network Policy Server (NPS) must be on different server than RD Gateway (otherwise MFA won't work). [2] This is in contrast to application streaming systems, like Microsoft App-V, in which computer programs are streamed to the client on-demand and executed on the client machine.
