Session Servers
Compaq Thin Client terminals can connect to Citrix ICA and
Microsoft RDP sessions running on remote servers.
ICA
ICA can be made available on the network using either of the
following services:
■
Microsoft Windows 2000 Server with Terminal Services and one
of the following installed:
❏
Citrix MetaFrame 1.8
❏
Cirtix MetaFrame XP
❏
Citrix Device Services (CDS)
■
Microsoft Windows NT 4.0 Terminal Server Edition with one of
the following installed:
❏
Citrix MetaFrame 1.8
❏
Citrix MetaFrame 1.0
❏
CDS
RDP
RDP can be made available on the network using any of the following
services:
■
Windows 2000 Server with Terminal Services installed
■
Windows NT 4.0 Terminal Server Edition
✎
If a Windows 2000 server is used, for both of these session services
(ICA and RDP) a Terminal Services Client Access Licenses (TSCAL)
server must also reside somewhere on the network. The server grants
temporary licenses (on an individual device basis) that are good for
90 days. Beyond that, you must purchase TSCALs and install them in
the TSCAL server (you cannot make a connection without a
temporary or permanent license).

Extended Windows NTe Features
The operating system of the Microsoft Windows NTe-based terminal
has extended features not found in the standard Microsoft
Windows NT operating system. With the exception of the Microsoft
Client Connection Manager and Citrix Program Neighborhood,
controls for extended Windows NTe features are only available
through Administrator logon accounts.
Ä
CAUTION: A write filter is employed on the terminal for security and to
prevent excessive flash write activity. Changes to the terminal
configuration are lost when the terminal is restarted unless the write
filter cache is flushed during the current boot session. See the write filter
topics later in this guide for instructions on how to flush the cache.
Logging On
Auto Logon as User is the factory default. You may use the Specify
Logon Information dialog box to disable/enable auto logon and to
specify the user name and password used for auto logon. If auto logon
is disabled, the entered default user name initially displays in the
logon dialog box, but the user must supply the logon box password.
Specify Logon Information Dialog Box
257363-001.book Page 2 Tuesday, October 8, 2002 1:05 PM
Quick Reference Guide 3
To disable auto logon:
1. Open the Specify Logon Information dialog box using the
special key sequence: Tab, Home, End,
←
,
→
. This dialog box
may also be opened by selecting Winlog in the Control Panel
window.
2. Select the Enable Auto Logon check box to enable automatic
logon (default is selected).
3. Type the logon information in the Default User Name and
Default Password text boxes:
❏
For a user logon account, enter an assigned user name in
Default User Name and enter the corresponding password in
Default Password. The factory-default user name and
password are both User (enter in both text boxes).
❏
For an administrator logon account, enter Administrator in
Default User Name and enter the password in Default
Password. The factory-default administrator password is
“Administrator”.
✎
For security purposes, it is recommended that the passwords be
changed from the defaults. An administrator can change passwords by
typing Ctrl+Alt+Del to open the Windows NT Security dialog box
and selecting Change Password. Passwords are case sensitive but
user names are not case sensitive.
✎
Upon closing the Specify Logon Information dialog box after
making changes, you are prompted to log off. If you shut down or
restart the terminal instead, the changes will be lost unless the write
filter cache is flushed before you restart or shut down the terminal.
✎
Additional user accounts may be created by a user manager tool
accessed through a network share. However, due to local memory
constraints, the number of additional users should be kept to a
minimum. Also, certain local settings are recommended for each new
user to configure the Start menu and to limit access to terminal
resources. See the “New Local User Account” section later in this
guide for additional information.

The NTe Desktop
This section gives a general overview of the NTe Desktop.
Write Filter
Upon logon the Wfilter status message box displays (unless display
was disabled either by using the check box or by editing the Windows
registry) for about 10 seconds. The status of the flash memory write
function can be ACTIVE (the default), INACTIVE, or DISABLED.
See Appendix A, “Application Notes”, later in this guide for more
information.
Wfilter Status Message Box
✎
A newly flashed terminal (new from the factory or immediately after
a firmware image upgrade) initially displays a one time only message
indicating that the system must be turned off and restarted to initialize
the write filter (Wfilter). The terminal automatically restarts. Ignore
and do not respond to any error messages that display during the
restart process. The message does not display on subsequent
terminal restarts.
Time Dialog Box
Upon logon the Dimension 4 time dialog box displays on the desktop
for a short period of time. The terminal time displays in the title bar of
the dialog box. The dialog box displays while the terminal
automatically synchronizes its local time with the time on the server.
For an administrator logon this dialog box may also be opened
257363-001.book Page 4 Tuesday, October 8, 2002 1:05 PM
Quick Reference Guide 5
through the Time Sync selection on the Control Panel (see the
section “Control Panel Extended Selections” later in this guide).
Instructions for using this dialog box are on the Web site referenced in
the About Dimension 4 message box (click the About button to open
the message box).
✎
If desired, an administrator may modify the Windows registry so that
the Dimension 4 dialog box does not display at logon (see the section
“Time Synchronization” later in this guide for instructions). However,
this may require the user to set the clock manually after each reboot.
This is because on some units there is no battery to keep the clock
running after power is turned off.
Dimension 4 Time Synchronization Dialog Box
User’s Desktop and Start Menu
The desktop that displays for a user log on is a standard Windows NT
desktop, except that the Citrix Program Neighborhood and Client
Connection Manager icons are present. These selections are also
257363-001.book Page 5 Tuesday, October 8, 2002 1:05 PM

Write Filter Cache
If changes have been made to the system configuration settings, that
you want to persist, you must flush the write filter cache during the
current boot session. Otherwise the new settings are lost when the
terminal is shut down or restarted. The write filter cache contents are
not lost when you simply log off and on again (as the same or
different user); that is, you may flush the write filter cache after the
new logon and still retain the changes. See the write filter topics later
in this guide for instructions on how to flush the cache.

You will be prompted to restart for changes to take effect, but make
sure to flush the write filter cache first.
Ramdisk Configuration Dialog Box
✎
The default RAM disk size may vary depending on the Thin Client
model and the installed memory size.
Time Sync
Time Sync launches the Dimension 4 time synchronization
application dialog box. Time Sync automatically starts each time a
user logs on. It searches for the designated time servers in sequence
until a connection is achieved, and uses the time furnished by the time
server to set the terminal time. The application then automatically
closes. If the application can not connect to a time server within
approximately 10 seconds (default, which can be changed) it
times-out and closes. If no time server is found, the terminal time can
be set manually on the terminal’s local clock.
If desired, you may prevent the time synchronization application from
starting at log-on by modifying the Windows Registry. See “Time
Synchronization” section of Appendix A for further instructions.
Winlog
Launches the Specify Logon Information dialog box which is used
to enter automatic and default logon information.

Appendix A - Application Notes
Write Filter
The write filter provides a secure environment for thin-client
computing. It does this by protecting the terminal from undesired
flash memory writes (flash memory is where the operating system
and functional software components reside). The write filter also
extends the life of the terminal by preventing excessive flash write
activity. It gives the appearance of read-write access to the flash by
employing a cache to intercept all flash writes and returning success
to the process that requested the I/O.
The intercepted flash writes stored in cache are available as long as
the terminal remains active but will be lost when the terminal is
rebooted or shut down. To preserve the results of writes to the
registry, favorites, cookies, and so on, the contents of the cache can be
“flushed” (transferred) to the flash on demand by Upgrade, Rapport,
Extract, or manually using the Write Filter Device Control dialog
box (Start > Programs> Write Filter). After the write filter has
flushed the cache, all future writes during the current boot session are
to the flash, with no further caching until a reboot occurs.
Joining a Domain
As an administrator you may join the terminal to a domain using the
Network utility in the Control Panel.
Drive Z:
Drive Z: is the onboard volatile memory (Ms-ramdrive) on the logic
board. Because drive Z: is volatile memory, it is recommended that
you do not use this drive to save data that you want to retain.
257363-001.book Page 16 Tuesday, October 8, 2002 1:05 PM
Quick Reference Guide 17
Drive C: and Flash
Drive C: is in the onboard non-volatile flash memory. It is
recommended that you do not write to drive C:. Writing to drive C:
reduces the size of the flash. If flash size is reduced to 3 MB, the
terminal becomes unstable. If flash size is reduced to 2 MB, the
terminal image will be irreparably damaged and it will be necessary
for you to contact an authorized Compaq service center to repair the
terminal. It is recommended that 5 MB be left unused.
The write filter (if ACTIVE) protects the flash from damage and
presents an error message if the cache overflows. However, if this
occurs you will not be able to flush the write filter cache and any
terminal configuration changes still in cache will be lost.
Items that are written to flash (or to the write filter cache) are:
■
Favorites
■
Created connections
■
Delete/edit connections
■
History
Saving Files
Ä
CAUTION: The terminal uses an embedded operating system with a
fixed amount of flash memory. It is recommended that you save files that
you want to retain on a server rather than on your terminal. Be careful of
application settings that write to the C: drive, which resides in flash
memory (in particular, many applications by default write cache files to
the C: drive on the local system). If you must write to a local drive,
change the application settings to use the Z: drive. To minimize writing
to the C: drive, the configuration settings described in the “New Local
User Account” section that follows should be made.
✎
Also, see the descriptions of the write filter and the need to flush the
cache to permanently save configuration data.
