Remote Desktop Connection (RDC) is a technology that allows you to sit at a computer/notebook and connect to a remote computer/server in a different location through the network. RDC is installed by default on all versions of Windows XP/Vista/7/8 Operating Systems (OS), but not at Windows 95/98/2000 OS.
Assumptions:
- Your own local computer/notebook is running Windows XP Professional SP3 OS. If you are connecting to a remote computer that is running Windows Vista or Windows Server 2008 OS, please download and installed the RDC Terminal Services Client 6.1 in order to make use of the new Remote Desktop Services features in it. This will update your Remote Desktop Protocol to version 6.1.
If you are connecting to a remote computer that is running Windows 7 or Windows Server 2008 R2 OS, please download and installed the Remote Desktop Connection 7.0 client update [for pc running Windows XP Service Pack 3 (SP3), Windows Vista Service Pack 1 (SP1), and Windows Vista Service Pack 2 (SP2)] in order to make use of the new Remote Desktop Services features in it. This will update your Remote Desktop Protocol to version 7.0. - If your own local computer/notebook is running Windows 7 Service Pack 1 (SP1) or Windows Server 2008 R2 Service Pack 1 (SP1) OS, please download and installed the Remote Desktop Protocol (RDP) 8.0 update in order to make use of the new Remote Desktop Services features. These features were introduced in Windows 8 and Windows Server 2012 R2 OS. This will update your Remote Desktop Protocol to version 8.0.
- You have login to the National University of Singapore (NUS) network using wired connection. If you are using wireless connection (NUS), please login to the WebVPN first before trying to make a RDC to the remote computer/server in NUS.
- Assume the remote computer/server is already powered on and no one has login to it.
Microsoft Remote Desktop Connection Client for Mac
Microsoft Remote Desktop Connection Client for Mac allows Macintosh computer users to connect to a remote Windows-based computer/server and work with programs and files on that remote Windows-based computer/server from their Macintosh computer.
- If your MAC OS X is v10.5.8 or later, please download and install “Microsoft Remote Desktop Connection Client for Mac 2.1.1” (for remote Windows-based computer/server running Windows XP/Vista/7/Server 2003 or 2008) or
- If your MAC OS X is v10.4.9 (Tiger) or later, please download and install “Microsoft Remote Desktop Connection Client for Mac 2.0.1” (for remote Windows-based computer/server running Windows XP/Vista/Server 2003 or 2008) or
- If your MAC OS X is v10.2.8 or later, please download and install "Remote Desktop Connection Client 1.0.3 for Mac" (for remote Windows-based computer/server running Windows NT Server 4.0/XP/Server 2000 or 2003). The Macintosh computer must be using Macintosh PowerPC Processor and the hard disk should be in Mac OS Extended (HFS+) format which is the default format for Mac. Microsoft does not currently support running Remote Desktop Connection from a hard disk that is in another format.
Please note that "Remote Desktop Connection Client 1.0.3 for Mac" will not work if the remote Windows-based computer/server is running Windows Server 2008 OS.
For MAC user to connect to the remote Windows-based computer/server from their Macintosh computer/notebook, please input Fully Qualified Domain Name (FQDN) or IP address of the remote Windows-based computer/server. For example, if the given remote Windows-based computer/server has a local hostname of remoteServerName and a parent domain name of stf.nus.edu.sg, the FQDN is "remoteServerName.stf.nus.edu.sg".

Create a Remote Desktop Connection
1. Assume you have already login to NUS network in your computer/notebook. For Windows XP/7 OS, kindly click Start → All Programs → Accessories → Remote Desktop Connection to open the RDC.
2. At the RDC window, under the General tab, in Computer:, kindly types the remote computer name or its IP address.
3. Kindly click the Experience tab, in Performance, kindly select "LAN (10 Mbps or higher)".
Most of the Experience settings are related to the graphical nature of the desktop. Because the processing for graphics happens on the remote computer and must be transmitted to the desktop over the network connection, you can increase performance by allowing only the minimal settings that are necessary for your users. For optimal performance, the below configurations are recommended:
Desktop Experience Settings
| Setting | Description |
| Desktop Background | Allows user to choose a custom background or wallpaper for their desktop. Because these can be very graphic-intensive, disable this setting unless it is necessary for your users. |
| Show contents of window while dragging | Redraws the contents of a window rather than showing just the frame of the window when you move the window across the screen. Because this redrawing takes place on the server and needs to be transmitted over the network connection to display on the user's desktop, disable this setting unless it is necessary. |
| Menu and window animation | Enables cascading menus and scroll transitions for menus and tool tips. Because this rendering takes place on the server and needs to be transmitted over the network connection to display on the user's desktop, disable this setting unless it is necessary. |
| Themes | Allows user to choose a background plus a set of sounds, icons, and other elements for their desktop. Because many themes are graphic-intensive, disable this setting unless it is necessary for your users. |
| Bitmap caching | Stores frequently used images on the local computer to speed up the connection. By enabling this setting, these images do not have to be transmitted across the network connection each time they appear on the desktop. This setting is enabled by default. |
4. Click Connect. The Credentials dialog box will appear:
In the Credentials dialog box, kindly type your UserID (nusstu\yourUserID for student or nusstf\yourUserID for staff) and Password, and then click OK to connect to the remote computer.
Copy and paste a file from a local computer to a remote computer

6. In the remote computer Windows Explorer, navigate to the file that you want to copy under the “D on yourComputerName
7. In the same remote computer Window Explorer, kindly navigate to the location on the remote computer where you want to paste the file, eg: Users (D:) drive. Right-click the drive/folder icon, and then click Paste to transfer the file from your local computer to the remote computer.
Method 2
If you are unable to use RDC to establish a connection to the remote computer, you can use this method provided that you have already configured a share folder at the remote computer.
1. Assume you have already login to NUS network and your d:\users\yourName
2. At the local computer, kindly open a Windows Explorer by clicking
Start → All Programs → Accessories → Windows Explorer
Kindly navigate in the Windows Explorer window to the file residing on your local computer that you want to transfer to the remote computer. Select the file, right-click and click Copy.
3. In the Windows Explorer Address, kindly type the remote computer name, eg: \\remotePcName
After a while, Windows Explorer will list those shared folders at the remote computer.
4. Kindly locate your remote share folder at the remote computer. Right-click on your remote share folder icon and click Paste to transfer your file from your local computer to the remote computer.
To disconnect (lock) without ending a session

- When using RDC in your Windows XP SP3 x86 OS computer to connect to a remote server that had configured RDC with Network Level Authentication (NLA) setting, you encountered the below error message:
The remote computer requires Network Level Authentication which your computer does not support. For assistant, contact your system administrator or technical support.
This is because your computer is either not running at least RDC version 6.0 or higher version, or the Credential Security Support Provider (CredSSP) is not turn on in your Windows XP SP3 x86 OS.
For pc running Windows XP SP2 x64 OS, the Network Level Authentication in RDC is not enabled by default. Microsoft does not provides any support on how to enable the Network Level Authentication in RDC for Windows XP SP2 x64 OS. Hence, user with Windows XP SP2 x64 OS pc cannot connect to a remote server that had configured RDC with Network Level Authentication (NLA) setting.
If your Windows XP SP3 x86 OS computer is running RDC below version 6.0, it does not support NLA. Please download and installed the Remote Desktop Connection 7.0 client update [for pc running Windows XP Service Pack 3 (SP3), Windows Vista Service Pack 1 (SP1), and Windows Vista Service Pack 2 (SP2)] in order to make use of the new Remote Desktop Services features in it.
CredSSP is a new Security Support Provider (SSP) that is available in Windows XP SP3 x86 OS by using the Security Support Provider Interface (SSPI). CredSSP enables a program to use client-side SSP to delegate user credentials from the client computer to the target server. Please refer to the Microsoft website on how to enable the CredSSP protocol via a registry modification on Windows XP SP3 x86 OS.
After turning on the CredSSP, you need to restart your computer for it to take effect before using RDC, or else you will encounter an error message "An authentication error has occurred (code: 0x507). Remote computer: xxx" when using RDC to connect to the remote computer. - When attempting to establish a Remote Desktop Connection using RD client (mstsc.exe) to a Remote Desktop server which is running Windows Server 2008 R2, you may encounter the below message:
The connection cannot be completed because the remote computer that was reached is not the one you specified. This could be caused by an outdated entry in the DNS cache. Try using the IP address of the computer instead of the name.
To resolve the issue, please login as a local administrator to the Remote Desktop (RD) server. Then, kindly change the remote desktop security on the RD server to RDP Security Layer to allow a secure connection using Remote Desktop Protocol encryption:
1. Navigate to Start > Administrative Tools > Terminal Services > Terminal Services Manager.
2. With RD Session Host Configuration selected view under Connections.
3. Right click RDP Listener (Connection Name: RDP-Tcp) with connection type Microsoft RDP 6.1 and choose Properties.
4. In the "General" tab of the properties dialog box under Security, select RDP Security Layer as the Security Layer. You can leave the "Encryption Level" as "Client Compatible".
5. Click OK.
Note: This setting does not need a restart of the Server or Remote Desktop Service. - Solved cannot copy and paste in the Remote Desktop Session (RDS)
The clipboard implements a "clipboard viewer chain" and is application-controlled. Every applications that is added to this "clipboard viewer chain" is responsible for passing on notification messages to the next viewer in the chain. There are applications that do not pass the messages and causes the copy and paste problem in the RDS.
For example, if you used FEKO application and had finished your FEKO simulations in the Windows Server Enterprise 2008 (x64) SP2 Operating System in the RDS of the remote machine, but encountered the copy and paste problem, the FEKO application might still be using the rdpclip.exe process (consumed about 8.2 GB of memory) and has not passed the notification messages to the next viewer in the "clipboard viewer chain".
Please use the Task Manager to kill the rdpclip.exe process and try the copy and paste again in the RDS of the remote machine. If the copy and paste problem is still not solved, please click "Start" -> "Run". Kindly type rdpclip.exe and click the OK button to restart the rdpclip.exe process to restore the clipboard communication.
