Remote Desktop Service

A remote desktop service is a protocol for giving access to a remote computer system by using a computer system or a device like a server with a login name and password. With the process, the user can access a computer system remotely and use it to access another machine or server that is connected to the same network.

Basically, the remote desktop is enabled when the user owns the computer system or the client is configured on the remote computer system. Later the user can log in to the remote computer system to use it. The remote desktop services can be used to access a machine even when the user is not connected to the local network.

Remote Desktop Services architecture is the basic infrastructure for offering the remote support solution to the client. The OSI model is used for defining the data link layer, data transfer layer, network layer, services layer, and remote procedures layer.

Using the OSI model, the Desktop layer is the lowest layer dedicated to the remote computer system. The computer that is owned by the client is connected to the remote computer system through the network and the user can log in to the computer system. The ownership model is beneficial because it ensures that the computer systems that are remote are authenticated. The users can gain access to the information that they want using the remote desktop service.

The Data Link layer offers the means through which the client can connect to the server. It can be a broadband connection through a secure router or through a Virtual Private Network (VPN) through either the LAN or through the Internet. The VPN services allow a remote user to access the private network from a remote location, allowing the remote user to work as if he is sitting at his desk. The Data Link layer offers the lowest level of service.

The Network layer helps the client to share the files, folders, and data between the computer and the server. The exact location of the data cannot be determined by the computer because it is copied to the server. The location of the data can be approximate.

On the other hand, the services layer allows the clients to extend the services that they have to the server, which extends the server jobs and capabilities. The server can be configured to provide the particular services that the client wants or even to simply not provide services at all if the client does not express the services that he needs.

The Remote procedure layer marks the place where the data of the remote computer can be stored, for example, in a file server. The desktop client browses through menus and the control panel remote procedure layer (DCL) is connected to the server.

The Desktop layer is the first level in the remote procedure layer. The components located in the layers below this are the server, the browser, the mail client, the news client, the fun client, the hardware, and the services.

In the desktop interface, the user can only display the properties of the remote computer. The DCL programs such as the desktop environment program and the remote procedure programs are loaded by the DCL automatically. All the devices that are connected to the computer during the desktop interface have to be configured in order to allow the computer to send and obtain data from them.

The remote procedure programs can be found by using the procedures keyword in the DCL. Two interfaces are used for the configuration of the remote PC. The keyword and the command line. When the router is connected to the remote PC, the router can be configured into the DCL or the trusted zone (the addresses range from to The advantage of this is that no PC is needed and everything is configured by the manufacturer.

The DCL interface’s creativeness switches off and on. They are basically flat wires with an on and off. The purpose is to send the commands to the router or the server. The routers and the servers have hosts names. These hosts can be changed at any time. What is remarkable about this is that these devices (known as PCs) can be found to the right of the router. All that is needed is a username and a password. These are known as SSID.

There are 3 different methods that can be used to change the setting of the username and the password. Firstly, the username can be changed directly without a password. Secondly, the password can be changed independently from the computer. That is, Changing the password does not require associating it with the router configuration. Changing the username is done in the background so it is not too visible.
