With early networks, users utilized dumb terminals (systems consisting of a monitor and keyboard without a processor) to connect to a mainframe. Later, computers could use telnet to connect to a server and execute commands at a command prompt. Remote Desktop Services, formerly known as Terminal Services, is one of the components of Microsoft Windows that allows a user to access applications and data on a remote computer over a network.
By default, Windows Servers are configured to use Remote Desktop for Administration licensing mode, which supports up to two remote sessions (three if you count the console session, which is the session that you use when you log on to the computer directly), and is primarily used to connect to a server to manage it. However, if you want to run applications that require more than the standard two remote sessions, you will need to first load and configure the computer running Windows Server 2008 R2 as a Remote Desktop Session Host server role. You will also need an RD licensing manager to keep track of the licenses used, and you will have to purchase and install terminal server licenses.
To access a computer running Remote Desktop Services, you would use Remote Desktop Connections to access a computer’s graphical user interface including the desktop, start menu, and programs just as if you were sitting in front of the computer. See Figure 1. Two technologies that allow you to remotely access a computer’s desktop are Remote Desktop and
Remote Assistance over TCP port 1389.
To connect to a remote computer:
• The computer must be turned on.
• It must have a network connection.
• Remote Desktop must be enabled in the System Properties.
• You must have permission to connect (be a member of the administrators group or the Remote Desktop Users group).
ENABLE REMOTE DESKTOP
To enable Remote Desktop:
1. Click the Start button. Right-click Computer and select Properties.
2. Click Remote Settings and select one of the following options:
• Allow connections from computer running any version of Remote Desktop (less secure).
• Allow connections only from computers running Remote Desktop with Network Level Authentication (more secure) options.
3. If you are prompted for an administrator password or confirmation, type the password
or provide confirmation.
4. Click Select Users. If you are enabling Remote Desktop for your current user account, your name will automatically be added to this list of remote users and you can skip the next two steps.
5. In the Remote Desktop Users dialog box, click Add. This will add users to the Remote Desktop Users group.
6. In the Select Users dialog box, enter the user’s name and click OK.
ACCESS REMOTE DESKTOP
To start Remote Desktop on the computer you want to work from:
1. Open Remote Desktop Connection by clicking the Start button, selecting Accessories, and selecting Remote Desktop Connection. You could also run the mstsc.exe command.
2. In Computer, type the name of the computer that you want to connect to and click Connect. (You can also type the IP address instead of the computer name if you want.) For more advanced options before the connection, click the Options button. See Figure 7-6.
RemoteApp (or TS RemoteApp) is a special mode of Remote Desktop Services that allows you to run an application in its own window instead of opening a session with Remote Desktop Connection. For the most part, the application looks like a normal application running on your local computer but in reality it is running remotely on a server. A RemoteApp can be packaged
either as a .rdp file or distributed via an .msi Windows Installer package.
Besides using a VPN tunnel, you can use a Remote Desktop Gateway (RD Gateway) role service to enable authorized remote users to connect to resources on an internal private network over the Internet using a Remote Desktop Connection (RDC) client. RD Gateway uses the Remote Desktop Protocol (RDP) over HTTPS to establish a secure, encrypted connection between remote users on the Internet and the internal network resources on which their productivity applications run.
If for some reason the Explorer taskbar is not available, you can also press the Ctrl+Alt+End keys to open the same window in Task Manager, from which you can start explorer.exe.
