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 Desktop 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 .
g
- 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 % bandwi dth 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 server, 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:
