Remote Desktop Services RDS , known as Terminal Services in Windows Server and earlier, [1] is one of the components of Microsoft Windows that allow a user to initiate and control an interactive session [2] on a remote computer or virtual machine over a network connection.
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. Starting with Windows , it was integrated under the name of Terminal Services as an optional component in the server editions of the Windows NT family of operating systems, [4] receiving updates and improvements with each version of Windows.
The first two are individual utilities that allow a user to operate an interactive session on a remote computer over the network. In case of Remote Assistance, the remote user needs to receive an invitation and the control is cooperative. In case of RDC, however, the remote user opens a new session on the remote computer and has every power granted by its user account’s rights and restrictions. For example, rdesktop supports Unix platforms.
Although RDS is shipped with most editions of all versions of Windows NT since Windows , [4] its functionality differs in each version. Other client versions of Windows only allow a maximum of one remote user to connect to the system at the cost of the user who has logged onto the console being disconnected. Windows Server allows two users to connect at the same time. This licensing scheme, called “Remote Desktop for Administration”, facilitates administration of unattended or headless computers.
Only by acquiring additional licenses in addition to that of Windows can a computer running Windows Server service multiple remote users at one time and achieve virtual desktop infrastructure. For an organization, RDS allows the IT department to install applications on a central server instead of multiple computers.
Such centralization can make maintenance and troubleshooting easier. RDS and Windows authentication systems prevent unauthorized users from accessing apps or data. 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.
In late December the two companies announced a five-year renewal of this arrangement to cover Windows Vista. The login subsystem winlogon. These executables are loaded in a new session, rather than the console session. The RdpDD. It also allows creation of virtual channels , which allow other devices, such as disc, audio, printers, and COM ports to be redirected, i. 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.
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. It also creates the other virtual channels and sets up the redirection. RDP communication can be encrypted; using either low, medium or high encryption.
With low encryption, user input outgoing data is encrypted using a weak bit RC4 cipher. With medium encryption, UI packets incoming data are encrypted using this weak cipher as well.
Terminal Server is the server component of Terminal services. It handles the job of authenticating clients, as well as making the applications available remotely. It is also entrusted with the job of restricting the clients according to the level of access they have.
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.
The remote session information is stored in specialized directories, called Session Directory which is stored at the server. Session directories are used to store state information about a session, and can be used to resume interrupted sessions.
The terminal server also has to manage these directories. Terminal Servers can be used in a cluster as well. In Windows Server , it has been significantly overhauled. While logging in, if the user logged on to the local system using a Windows Server Domain account, the credentials from the same sign-on can be used to authenticate the remote session.
In addition, the terminal server may be configured to allow connection to individual programs, rather than the entire desktop, by means of a feature named RemoteApp. Terminal Server can also integrate with Windows System Resource Manager to throttle resource usage of remote applications. It can be used to configure the sign in requirements, as well as to enforce a single instance of remote session. 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.
This is also available for iOS and Android. The client allows users to connect to their remote apps or to their remote desktops without using an installed remote desktop client. The RDP 6. The UI for the RemoteApp is rendered in a window over the local desktop, and is managed like any other window for local applications.
The end result of this is that remote applications behave largely like local applications. The task of establishing the remote session, as well as redirecting local resources to the remote application, is transparent to the end user. A RemoteApp can be packaged either as a. When packaged as an. It will invoke the Remote Desktop Connection client, which will connect to the server and render the UI. 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.
Opening a file registered with RemoteApp will first invoke Remote Desktop Connection, which will connect to the terminal server and then open the file. Any application which can be accessed over Remote Desktop can be served as a RemoteApp. 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.
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.
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.
The functionality is only provided via a public API , which can be used by any application to provide screen sharing functionality. Multiple viewer objects can be instantiated for one Session object. 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. Per-application filters capture the application Windows and package them as Window objects.
It contains an authentication ticket and password. The object is serialized and sent to the viewers, who need to present the Invitation when connecting. It allows a user to remotely log into a networked computer running the terminal services server. RDC presents the desktop interface or application GUI of the remote system, as if it were accessed locally. With version 6. In this scenario, the remote applications will use the Aero theme if the user connects to the server from a Windows Vista machine running Aero.
With resource redirection, remote applications can use the resources of the local computer. Audio is also redirected, so that any sounds generated by a remote application are played back at the client system. RDC prioritizes UI data as well as keyboard and mouse inputs, as opposed to print jobs or file transfers. It redirects plug and play devices such as cameras, portable music players, and scanners, so that input from these devices can be used by the remote applications as well.
There have been numerous non-Microsoft implementations of clients that implement subsets of the Microsoft functionality for a range of platforms. The most common are:. From Wikipedia, the free encyclopedia.

Но решил этого не делать. – Позвони коммандеру. Он тебе все объяснит. – Сердце его колотилось. Как все это глупо, подумал он, быстро выпалил: – Я люблю тебя! – и повесил трубку.
