 Windows XP Embedded Desktop
User
 When a user logs in, the User Desktop appears, as shown in the figure below. The default icons that 
appear on the User Desktop are Citrix Program Neighborhood, Remote Desktop Connection and 
Internet Explorer. You can also run this connection from the Start menu. The audio volume icon, VNC 
server icon and system time are displayed on the User Taskbar.  
When logged on as a user, there are many restrictions
 that protect the system from incorrent user 
actions. You cannot access the system drives and th ere are restrictions on configuring properties for 
them. To configure the client’s advanced and detailed settings, log on as an administrator.
Administrator
  If you logon as Administrator, the Administrator Desktop appears, as shown in the figure below. The 
default icons that appear on the Administrator Desktop are My Computer, My Network Places, Citrix 
Program Neighborhood, Remote Desktop Connection, Internet Explorer, and Recycle Bin. You can 
also run the Citrix Program Neighborhood, Remote De
sktop Connection, and Internet Explorer from the 
Start menu. The audio volume icon, VNC server icon,  Enhanced Write Filter status icon, and system 
time are displayed on the Administrator Taskbar. The  Administrator privilege is required for adding and 
removing programs.  
 
Log off, Restart, Shut down
  - To log off the current session, shut down or restart your client, use the Start menu. Click Start 
→ 
Shut down. The Shut Down Windows dialog box is displayed. Select an operation from the combo 
box and click OK. You can also log off or shut down your client using the Windows Security dialog 
box displayed when pressing the Ctrl + Alt + Del keys. If ‘Force Auto Log on’ is activated, you will be 
immediately logged on after each log off.
 
- The Client Log off, Restart and Shutdown take effect on the operations of the EWF(Enhanced Write  Filter). To keep the changed system configuration, you must save a cache for the current system 
session into flash memory. Failing to do so will cause the changed configuration to be lost when the 
client is shutdown or restarted. (In the case of  logging off, the configuration is remembered when 
loggin in again.)  For more information on the Enhanced Write Filter, refer to the Program Help  .
 
						

							 
 
 
 
 Programs
 - XPe Client is a client/server-based computing platform. On this platform, the client accesses the 
server each time it needs a program and it only receives the user interface screens from the server. 
Hence, various programs, such as ICA, RDP, and VNC, which are installed on a XPe Client, are 
used to help the client access the server and perform user tasks.
Citrix Program Neighborhood
Independent Computing Architecture (ICA) allows you to use applications on the server through a wide 
range of platforms and networks regardless of their basis.  
The ICA MetaFrame Server separates the application’s internal logic from the user interface. Due to this 
separation, users only work with the user interface on the client. The actual application is 100% run on the 
server. In addition, running an application through ICA only uses approximately 10% bandwidth compared 
to running it locally. By using this feature of ICA, users can do more work on the client than working locally. 
The core technologies of ICA are as follows:
    
Thin Resource
  - Low system requirements needed for running ICA; a computer equipped with an Intel 286 
processor and 640K RAM is sufficient. This means ICA can be run on any computer that exists at 
present.
Thin Wire
  - The default bandwidth required by ICA protocol is
 20 kbps, on average. Therefore, even with a 
Dial-Up or ISDN connection, a consistent performance is maintained. Any program, however large 
it is, can be run stably at a low bandwidth.
Universal Application Client
  - The Citrix ICA protocol separates the user interface from the application. While an application is 
running on the WinFrame multi-user application se
rver, its user interface is running on the thin 
client software of WinFrame. Hence, in any environment, it is possible to run applications fast. 
Platform Independent
  - ICA is inherently being operated regardless of the operating system platform. Because the clients 
for UNIX, OS/2, Macintosh, and Non-DOS are already on the market, you can run Windows 
applications on these operating systems.
  
The Citrix Program Neighborhood is a program that manages these ICA connections. To start the Citrix 
Program Neighborhood, select Start  → Programs 
→ Citrix 
→ MetaFrame Access Clients 
→ Program 
Neighborhood, or double-click the Citrix Program Neighborhood icon.  
  To create a new ICA connection, double-click the Add ICA Connection icon and follow these steps:  
 
 
 
 
 
1. Select the type of connection to create.  
 
 
						

							 
 
 
2. Type the connection name and the server name (IP address or DNS name).    
 
 
3. Configure the degree of compression for the data to be sent and received, and the degree of  reliability for sessions.  
 
 
 
4. To login to the server automatically, enter your username, password and domain. If you do not enter 
them now, you will be prompted to enter them whenever you connect to the server.  
 
 
						

							 
 
5. You can specify the color and size of the window to be displayed.    
 
 
6. If a connection succeeds, the server’s desktop appears on the client. In this step, you can make an  application run automatically.  
 
 
 
7. Click Finish to complete creating the new connection.

The Remote Desktop Connection
  You can control a running terminal server or another computer (Windows 95 or later) remotely through 
a remote desktop connection.
  Remote Desktop  
 
- Windows XP Professional or Windows 2000/2003 Server must be installed on the computer to 
be controlled remotely. This computer is called a host.
-
A remote computer running on an operating system later than Windows 95 is required. This 
remote computer is called a client. The client software for the remote desktop connection must 
be installed on the client.
- You must also be connected to the Internet. A broadband Internet connection is good for high 
performance. However, because the remote desktop transmits a minimum set of data including 
the display data and keyboard data to control the host remotely, a broadband Internet 
connection is not required. You can run a remote desktop on a low bandwidth Internet 
connection.
When running a remote desktop on Windows XP Pr ofessional, you cannot use the operating 
system of your computer.
   
Enabling Your Computer as the Host  
 
You must enable the Remote Desktop feature to control it from another computer. You must be 
logged on as an administrator or a member of the Administrators group to enable Remote Desktop 
on your computer. Follow these steps: 
 
 
- Open the System folder in the Control Panel. Click Start, point to Settings, click Control Panel, 
and then double-click the System icon.
- On the Remote tab, select the “Allow users to connect remotely to this computer” checkbox.
- Ensure that you have the proper permissions to connect to your computer remotely, and click  OK.
- Leave your computer running and connected to the client’s network with Internet access.
  
 
 
						

							 
 
 
 
 
  Start a Remote Desktop Session on the Client  
 
Once you have enabled your host computer to allow remote connections and installed the client 
software on a Windows-based client computer, you are ready to start a Remote Desktop session.  
You must first establish a virtual private network connection or remote access service connection 
from your client computer to your host computer. 
 
 
1. Click Start, point to Programs, and then click Remote Desktop Connection. Or double-click the  Remote Desktop Connection icon.  
The Remote Desktop Connection window will open. 
 
2. Enter the host computer name. You can configure det ailed settings by clicking the Options button.  
 
 
3. Options    
- General: Enter the login information to connect to the host computer. Enter your username and 
password to login to the host automatically.  
 
 
						

							 
 
- Display: The Remote Desktop Connection sends and receives compressed screen data. If you set 
the resolution and color quality to the high option, the speed may become slow.  
 
 
- Local Resource: Specify whether to use the hard disks and ports.  
 
						

							 
 
- Programs: Specify whether to display the Desktop or run an application whenever you are 
connected. The default is ‘Desktop’.  
 
 
 
 
- Experience: You can select your connection speed, and select and share environmental options.  
 
 
						

							 
  
4. Click Connect. The Log On to Windows dialog box appears.    
5. In the “Log On to Windows” dialog box, type your  username, password, and domain (if required), and 
then click OK. The Remote Desktop window will open and you will see the desktop settings, files, and 
programs that are on the host computer.  
   For more information on Remote Desktop Connections, visit the  Microsoft web site.  RealVNC Server 
  RealVNC (Virtual Network Computing) is a software program that allows you to connect to another 
computer on a network and control it remotely. Compared to the Windows terminal service which has a 
similar function, RealVNC allows only one administrator to connect to the server at a time. That is, if 
another is connected to the server as an administrato
r, the previous administrator connection will be 
disconnected.  
In RealVNC, the server and the viewer communicate via the VNC protocol. You must install a RealVNC 
server on the computer you wish to control remotely, and a VNC viewer on the computer which 
remotely controls the computer where the RealVNC server is installed. Hence, the RealVNC server 
program is installed on a XPe client.  
 
By using this program, you do not have to move directly to the client site to resolve its problems. 
Instead, you can connect to the client from the server and solve problems remotely. For this reason, 
RealVNC is being used very usefully.  
Only administrators can configure the RealVNC server  properties. To display the configuration dialog 
box for RealVNC, double-click the RealVNC icon in th e system tray. From this dialog box, you can run 
a VNC server and configure a password and variou s properties. The default password is set to 
‘Administrator’. Note that it is case-sensitive.
  
 
 
						

							 
 
 
 
 
 
Internet Explorer 
 
A XPe Client includes Internet Explorer. This program is permitted for all users. For more information 
on Internet Explorer, visit the  Microsoft website.
  
Enhanced Write Filter 
  Enhanced Write Filter (EWF) protects a flash volume
 from write access and consequently, preserves 
the durability of the flash device. EWF provides read and write access through a cache to the client 
instead of allowing direct access to a flash volume.  
 
If EWF is activated, data is not stored to the flash. The data stored in the cache is only effective while 
the client is operating. The cached data will be lost when restarting or shutting down your client. 
Therefore, to store the data written to the registry,  favorites and cookie folders, etc., the content stored 
in the cache should be transferred to the flash.  An error message is displayed when it is not possible 
to write to the cache due to a lack of memory. If this message is displayed, you have to deactivate 
EWF to flush the EWF cache. The user can double-click the EWF icon on the tray at the bottom right of 
the screen to call the EWF Manager. A user can also change the EWF configuration by entering EWF 
management commands at the command prompt. This task requires the administrator privilege.  
 
  Enable disk write protection and restart your computer  
 
- If the EWF is disabled, enable it. If this item is selected, the cache is flushed and the EWF is
