Frequently asked questions about Remote Desktop Connection

Edit


With Remote Desktop Connection, you can easily connect to a remote computer running Windows. All you need is network access and permissions to connect to the other computer. You can also specify special settings for your connection, and then save the settings for the next time you connect.
Remote Desktop Connection is a technology that allows you to sit at a computer and connect to a remote computer in a different location. For example, you can connect to your work computer from your home computer and have access to all of your programs, files, and network resources as though you were in front of your computer at work. You can leave programs running at work and when you get home, you will see your work computer's desktop displayed on your home computer, with the same programs running.
Also known as a fully qualified domain name (FQDN), a full computer name includes the host (computer) name, the domain name, and all the higher level domains. For example, the full computer name of a computer named "host" might be host.example.microsoft.com.
Use authentication when you want to securely verify that you are connecting to the correct computer. Your network administrator might also require you to use authentication.
In Remote Desktop Connection, server authentication verifies that you are connecting to the correct remote computer, or server. This security measure helps prevent the interception of data by an unauthorized remote computer. There are three available authentication options:
  • Always connect, even if authentication fails (least secure): With this option, even if Remote Desktop Connection cannot verify the identity of the remote computer, it connects anyway.
  • Warn me if authentication fails (more secure): With this option, if Remote Desktop Connection cannot verify the identity of the remote computer, it warns you so that you can choose whether to proceed with the connection or not.
  • Don't connect if authentication fails (most secure): With this option, if Remote Desktop Connection cannot verify the identity of the remote computer, you won't be able to connect.
To change authentication options, open Remote Desktop Connection, click Options, and then click the Advanced tab. If you're not sure which option to choose, ask your system administrator or the owner of the remote computer.
Remote computers that are running Windows Server 2003 with Service Pack 1 (SP1) or earlier operating systems cannot provide their identity for verification. If you know that the remote computer is running one of those operating systems, you can avoid authentication warnings by choosing Always connect, even if authentication fails, and then saving that change by clicking Save or Save As on the General tab.
The default option is "Always connect, even if authentication fails." To change it for future use, select the authentication level you want, and then, on the General tab, click Save or Save As to save your settings to an .rdp file. To connect to the same remote computer in the future, double-click the .rdp file.
Network Level Authentication (NLA) is a new authentication method that completes user authentication before you establish a full Remote Desktop connection and the logon screen appears. This is a more secure authentication method that can help protect the remote computer from hackers and malicious software. The advantages of NLA are:
  • It requires fewer remote computer resources initially. The remote computer uses a limited number of resources before authenticating the user, rather than starting a full Remote Desktop connection as in previous versions.
  • It can help provide better security by reducing the risk of denial-of-service attacks (attempts to limit or prevent access to the Internet).
  • It uses remote computer authentication, which can help protect people from connecting to remote computers that are set up for malicious purposes.

To find out if your computer is running a version of Remote Desktop with NLA

  1. Open Remote Desktop Connection.
  2. Click the icon in the top left corner of the Remote Desktop Connection dialog box, and then click About.
  3. Look for the phrase "Network Level Authentication supported" on the About Remote Desktop Connection dialog box.
A Terminal Services Gateway (TS Gateway) server is a type of gateway that enables authorized users to connect to remote computers on a corporate network from any computer with an Internet connection. TS Gateway uses Remote Desktop Protocol (RDP) along with HTTPS to help create a more secure, encrypted connection.
In earlier versions of Remote Desktop Connection, people could not connect to remote computers across firewalls and network address translators because port 3389—the port used for Remote Desktop connections—is typically blocked to enhance network security. However, a TS Gateway server uses port 443, which transmits data through a Secure Sockets Layer (SSL) tunnel.
A TS Gateway server provides these benefits:
  • Enables Remote Desktop connections to a corporate network from the Internet without having to set up a virtual private network (VPN) connection.
  • Enables connections to remote computers across firewalls.
  • Allows you to share a network connection with other programs running on your computer. This enables you to use your ISP connection instead of your corporate network to send and receive data over the remote connection.
Ask your network administrator whether you need to specify a TS Gateway server.
To specify a TS Gateway server:
  1. Open Remote Desktop Connection by clicking Start, clicking Programs or All Programs, clicking Accessories, and then clicking Remote Desktop Connection.
  2. Click Options, click the Advanced tab, and then, under Connect from anywhere, click Settings.
  3. Select Use these TS Gateway server settings, and then type the server name (ask your network administrator for this information).
  4. Select one of the three available logon methods:
    • Allow me to select later. This option lets you select a logon method when you connect.
    • Ask for password. This option prompts you for a password when you connect.
    • Smart card. This option prompts you to insert a smart card when you connect.
  5. Select or clear the Bypass TS Gateway server for local addresses check box.
Selecting this check box prevents traffic to and from local network addresses from being routed through the TS Gateway server, which makes your connection faster.
Note
  • Your network administrator might not allow changes to TS Gateway server settings.
Remote Desktop Connection supports high-resolution displays that can be spanned across multiple monitors. The monitors must be the same height and aligned side by side. To have the remote computer's desktop span two monitors, type Mstsc /span at a command prompt.
This feature is sometimes called continuous resolution. To toggle in and out of full-screen spanned mode, press CTRL+ALT+BREAK.
For additional security, you can change the port that Remote Desktop Connection uses (or "listens on"), instead of using the standard port 3389. When you log on, type the remote computer name, followed by a colon and the desired port (for example, Computer1:3390).
Remote Programs is a feature in Windows that allows you to connect to a remote computer and use programs installed on it. For example, your workplace might have a remote computer that you and other employees can connect to and run Microsoft Word. The experience is the same as running a program installed on your computer.
Remote Programs makes system administration easier because there is only one copy of a program to upgrade or maintain, rather than many copies installed on individual computers.

What problem are you having?
Cause:  When the dialog box asking you whether to use HyperTerminal as your telnet default client first appeared, you responded No and selected Stop asking me this question
Solution:   Open Registry Editor. In Registry Editor, navigate to the following registry key and change the value to 1:
HKEY_LOCAL_USER\Software\Microsoft\HyperTerminal\Telnet  Check.
After you change this value, the next time you start HyperTerminal, the dialog box will appear and will ask you whether you want to have HyperTerminal as your default telnet application.
Notes
  • To open Registry Editor, click Start, click Run, type regedit, and then click OK.
Caution
  • Incorrectly editing the registry may severely damage your system. Before making changes to the registry, you should back up any valued data on the computer. You can also use the Last Known Good Configuration startup option if you encounter problems after manual changes have been applied
  • changes have been applied.
Cause:  The HyperTerminal terminal screen size is determined by the font size that you are using. It will size itself to display 24 lines of 80 (or 132) characters of whatever font you have selected.
Solution:  On the HyperTerminal View menu, select Font. If you want a larger terminal screen select a larger font size. If you want a smaller terminal screen, select a smaller font size.
Cause:  The terminal screen displays the information sent from the remote computer, not information entered on your local computer. In order to view what you type, the remote computer must be configured to echo back your input. There also may be a time lag between when you type the information and when it is displayed on your terminal screen.
Solution:  Ensure that you have a proper connection with the remote computer and ensure that the remote computer is configured to echo user input.
Cause:  You are not using the Terminal font.
Solution:  On the HyperTerminal View menu, select Font. Click Terminal and choose OK.
Cause:  The Redial on busy option may not be selected
Solution:  On the HyperTerminal File menu, select Properties. Select the Connect To tab and ensure that Redial on busy is selected.
Cause:  You have not selected the correct terminal emulation type.
Solution:  On the HyperTerminal File menu, select Properties. Select the Settings tab. In the Emulation drop down box, choose the terminal type of the remote computer. If the remote computer's type is not listed in the drop down box, it is not supported by HyperTerminal.
Cause:  The remote computer that you are connected to has control of the characters displayed on your terminal screen. The remote computer is expecting the cursor to be at particular positions on the screen based on the data that it has already sent to the screen. If you alter that screen locally, you potentially disrupt the interaction between you and the remote computer in ways that the host can not predict or control. Therefore, HyperTerminal does not allow you to delete characters from the screen
Solution:  Not Applicable
Cause:  If you are set to Terminal Keys in the properties for this connection, pushing CTRL+V will send out the emulator escape sequence. Many hosts use CTRL+V to navigate through their systems.
Solution:  You can change this setting to Windows Keys and CTRL+V will work properly. To do so, on the HyperTerminal File menu, click Properties. Click the Settings tab, and click the Windows Keys radio button.
Important
  • When using the Windows Keys setting, all function, arrow and control keys will be processed locally. Using the Terminal keys setting and then using the menus to paste is the recommended option.
