Winterm9000 Series Reference  
Guide  
Introduction  
WintermTM 9000 Series Thin Clients use the WindowsTM XP embedded (XPe) operating  
system. The WintermTM 9000 Series Thin Clients provide access to applications, files, and  
network resources made available on machines hosting CitrixTM ICA and MicrosoftTM RDP  
session services. The keyboard, mouse, audio/video, and display data are transmitted  
over the network between the Thin Clients and session servers.  
Thin Client emulation software is installed locally by default. Other locally installed  
software permits remote administration of the Thin Clients and provides local maintenance  
functions.  
WintermTM 9000 Series XPe-based Thin Clients currently include the Models 9235LE,  
9440XL, 9450XE, 9455XL, 9650XE, Model J400, Product 941GXL, and Model x150,  
Product 9150SE.  
The latest WyseTM firmware version release for the 9235LE, 9450XE, 9455XL, 9650XE,  
Model J400, Product 941GXL, and Model x150, Product 9150SE is based on the  
Microsoft XPe SP1 release.  
The latest Wyse firmware version release for the 9440XL is based on the original release  
of Microsoft XPe.  
About This Guide  
This reference guide supplements the standard Windows XP and Windows XPe  
documentation supplied by Microsoft Corporation. The guide explains the differences,  
enhancements, and additional features provided by Wyse with the Thin Client. It does not

Terminal Emulation Support  
Third-party terminal emulation software can be installed on the Thin Client to support  
computing on legacy platforms. Access to accounts on these machines is the  
responsibility of the Thin Client user. The terminal emulation software uses the Telnet  
protocol to communicate with the computing platform.  
Support Servers  
The following services are required:  
Rapport Remote Administration  
®
You must install Wyse Rapport version 4.4 (installed on Windows XP Pro Workstation or  
Windows 2000 Server, Advanced Server or Workstation), and be able to access a  
software repository for your Thin Client (for information on installing Rapport and  
configuring the server environment, refer to the Rapport Quick Start Guide or Wyse  
Rapport Help File).  
Rapport accesses your Thin Client through the factory-installed Rapport® Agent and  
Preboot Execution Environment (PXE) client utilities. PXE upgrade services and Virtual  
Network Computing (VNC) Viewer are built-in to Rapport (see “Virtual Network Computing  
The Workgroup Edition of Wyse Rapport® is suitable for managing up to 750 client Thin  
Clients. It is provided with the Thin Client without charge.  
The Enterprise Edition of Wyse Rapport® is designed to manage larger numbers (greater  
than 750) of client Thin Clients. For information about obtaining or upgrading to the  
Enterprise Edition of Rapport contact Wyse Sales or Service (see “Ordering Information”  
on page v).  
Virtual Network Computing (VNC) Viewer  
VNC Server is factory-installed on your Thin Client and is, by default, automatically  
launched on log-on. It allows a Thin Client to be operated/monitored (shadowed) from a  
remote machine on which VNC Viewer is installed (primarily for troubleshooting and  
support purposes). The administrator uses a VNC Server dialog box that allows a  
password to be changed and properties to be set for a Thin Client. An administrator  
wanting to shadow a Thin Client must run the VNC Viewer component on the remote  
machine (accessed either from the Rapport Administrative Software or from a separate  
installation). The administrator using the VNC Viewer must know the password to the  
server component on a machine as well as a machine’s IP address or valid DNS name.  
For information about VNC, refer to “WinVNC” on page 56.

Extended XPe Features  
The WintermTM 9000 Series Thin Client’s operating system has extended features not  
found in standard Windows XP. Controls for extended XPe features are available only  
through an Administrator logon account—with exceptions of the Citrix Program  
TM  
Neighborhood, the Microsoft Terminal Server Client (Remote Desktop Connection  
Manager), and if installed, a special-order terminal emulation application.  
Logging On  
Users can log-on automatically or manually.  
Automatic Log-on  
The default for the XPe-based Thin Client is automatic log-on. The administrator can use  
the Winlog applet in the Control Panel to enable/disable auto logon and change the auto  
logon user name, password, and domain. Only the administrator logon account can  
change auto logon properties.  
Note  
To save the changes, be sure to flush the Write Filter cache at any time  
during the current system session. For information about the Write Filter and  
procedures for flushing the cache, refer to “Write Filter” on page 41.  
The Log-on to Windows dialog box is bypassed if automatic log-on is enabled. If you want  
to log-on as a different user while auto logon is enabled, log off while holding down the  
Shift key. This will cause the Log-on to Windows dialog box to display and allow you to  
manually enter the log-on information.  
Manual Log-on  
When automatic log-on is not enabled, upon Thin Client startup the Log-on to Windows  
dialog box displays.  
Type the log-on information in the User Name and Password text boxes:  
·
For a user log-on account, the factory-default user name and password are both  
User.  
·
For an administrator log-on account, the factory-default user name and password  
are both Administrator.  
Note  
Passwords are case sensitive but user names are not case sensitive.  
Caution  
For security purposes it is recommended that all passwords be changed from  
the defaults. An administrator can change passwords by using the  
Ctrl+Alt+Del key combination to open the Windows Security dialog box and  
then clicking Change Password. The password can not be changed when  
logged-on as a user.

16  
Note  
The administrator can create additional user accounts by using the User  
Manager utility available through the Control Panel. However, due to local  
memory constraints, the number of additional users should be kept to a  
minimum. For administrator information on user accounts, refer to “User  
Automatically Launched Utilities  
The following utilities are automatically launched:  
Write Filter  
Upon system start, the Write Filter utility is automatically launched. The Write Filter  
provides security and protects the flash memory from excessive write activity. The active/  
inactive status of the Write Filter is indicated by the color of the Write Filter status icon in  
the system tray of the desktop taskbar. For detailed information about the Write Filter, refer  
Note  
Changes made to the Thin Client configuration are lost when the Thin Client  
is restarted unless the Write Filter cache is flushed during the current system  
session. For procedures on flushing the cache, refer to “Write Filter” on  
NetXClean  
Upon system start, the NetXClean utility is automatically launched. NetXClean is a  
clean-up utility that keeps extraneous information from being stored on the local disk. For  
detailed information on this utility, refer to “NetXClean Utility” on page 48.  
VNC Server  
Upon Thin Client log-on, the Windows VNC Server utility is automatically launched. VNC  
allows the Thin Client’s desktop to be accessed remotely for administration and support.  
For detailed information about VNC, refer to “WinVNC” on page 56.  
Time Synchronization Utility  
Upon Thin Client log-on, the time synchronization utility dialog box briefly displays. This  
feature can be disabled by the administrator (locally or remotely) if desired.

Note  
If automatic log-on is enabled, when you log off (without shutting down) the  
Thin Client immediately logs on the default user. For instructions on logging  
on as a different user, refer to “Logging On” on page 15.  
The following utilities are affected by logging off, restarting, and shutting down the Thin  
Client:  
Write Filter cache - If you make changes to system configuration settings and want  
them to persist, you must flush the Write Filter cache during the current system  
session. Otherwise, the new settings will be lost when the Thin Client 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 can flush the Write Filter cache after  
the new log-on and still retain the changes. For instructions on flushing the Write Filter  
cache, refer to “Write Filter Control Dialog Box” on page 46. For general information  
about the Write Filter, refer to “Utilities and Settings” on page 41.  
Note  
A User log-on account does not have cache flush privileges; this is a local or  
remote administrator function.  
NetXClean Utility - NetXClean is a clean-up utility that keeps extraneous information  
from being stored on the flash memory. Clean-up is triggered automatically on restart,  
shut down, or user log off. For details about NetXClean, refer to “NetXClean Utility” on  
Power Management - A Monitor Saver turns off the video signal to the monitor,  
allowing the monitor to enter a power-saving mode after a designated idle time.  
Parameters for this mode are available by clicking Start | Settings | Control Panel |  
Screen Saver | Power.  
Wake-on-LAN - This standard XP feature allows the Rapport Administrative Software  
to perform image updates and remote administration functions at any time. To use this  
feature, the Thin Client power must remain on.  
Thin Client Time - After power off, clock time will not be lost as long as the power  
source remains on. Clock time will be lost if the power source is off and the battery  
option is not installed. The local time utility can be set to synchronize the Thin Client  
clock to a time server automatically (at a designated time) or manually.

Utilities and Settings  
The following utilities and settings are available for administrative use:  
Write Filter  
The Write Filter provides a secure environment for thin-client computing by protecting the  
Thin Client from undesired flash memory writes (flash memory is where the operating  
system and functional software components reside). By preventing excessive flash write  
activity, the Write Filter also extends the life of the Thin Client. 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 Thin Client  
remains active but are lost when the Thin Client is restarted or switched off. To preserve  
the results of writes to the registry, favorites, cookies, and so on, the contents of the cache  
can be transferred (flushed) to the flash on demand by the Rapport Administrative  
Software or manually using the Write Filter Control dialog box (see “Write Filter Control  
Dialog Box” on page 46). It can be opened either through the Start | Run command line  
(wtflush), by clicking Start | Programs | Control Panel | Administrative Tools | Write  
Filter, or by clicking Start | Programs | Write Filter. After the Write Filter has flushed the  
cache, all future writes during the current system session are written to the flash, with no  
further caching until a system restart occurs. The Write Filter can also be enabled/disabled  
through the command line or through the Write Filter Enable/Disable desktop icons. The  
status (enabled/disabled) of the Write Filter is displayed by the Write Filter status icon on  
the taskbar system tray (green indicates that the Write Filter is enabled, and red indicates  
that the Write Filter is disabled).  
Note  
When administering the Thin Client for permanent changes:  
-To avoid flash corruption, it is strongly recommended to flush the Write Filter  
cache immediately following a fresh restart before making permanent  
modifications to the system.  
-Do not flush the cache if the Thin Client has been used in the current system  
session.  
Caution  
The Write Filter cache should never be flushed if it is eighty-percent or more  
full. The administrator should periodically check the status of the cache and  
restart the Thin Client if the cache is more than eighty percent full.

42  
Note  
A Terminal Services Client Access License (TSCAL) is always preserved  
regardless of Write Filter state (enabled or disabled).  
If you want to have other registry settings preserved regardless of Write Filter  
state, contact support for help at http://www.wyse.com.  
For procedures on manipulating the Write Filter, refer to:  
Password Change with the Write Filter  
On Microsoft Windows NT-based computers and on Microsoft Windows 2000 or  
2003-based computers, machine account passwords are regularly changed with the  
domain controller for security purposes. By default, on Windows NT-based computers, the  
machine account password automatically changes every seven days. On Windows 2000  
or 2003-based computers, the machine account password automatically changes every  
30 days. The same is applicable for WintermTM 9000 Series Thin Clients if they are a  
member of a domain.  
With the Write Filter enabled, a Thin Client will successfully make this change with the  
domain controller. Because the Write Filter is enabled, however, the next time the Thin  
Client is booted it will not retain the new password. In such cases, you can use the  
following options:  
Disable the machine account password change on a WintermTM 9000 Series Thin  
Client by setting the DisablePasswordChangeregistry entry to a value of 1.  
Disable the machine account password change in Windows NT 4.0 or in Windows  
2000 or 2003, by setting the RefusePasswordChangeregistry entry to a value of 1  
on all domain controllers in the domain instead of on all workstations. WintermTM 9000  
Series Thin Clients will still attempt to change their passwords every 30 days, but the  
change will be rejected by the server.  
Note  
On Windows NT 4.0 domain controllers, you must change the  
RefusePasswordChangeregistry entry to a value of 1 on all Backup  
Domain Controllers (BDCs) in the domain before you make the change on  
the Primary Domain Controller (PDC). Failure to follow this order will cause  
event ID 5722 to be logged in the event log of the PDC.  
If you set the RefusePasswordChangeregistry entry in the Windows 2000  
or 2003 Domain Controller to a value of 1, the replication traffic will stop, but  
not the Thin Client traffic. If you also set the DisablePasswordChange  
registry entry to a value of 1 in the Thin Client, both Thin Client and  
replication traffic will stop.

Write Filter Command Line Control  
There are several Start | Run command lines you can use to control the Write Filter.  
Note  
Command line arguments cannot be combined.  
Caution  
Thin Client Administrators should use NT file security to prevent undesired  
usage of these commands.  
Use the following guidelines for the Start | Run command line option for the Write Filter:  
wtflush.exe with no arguments - Opens the Write Filter Control dialog box. For a  
description of the dialog box, refer to “Write Filter Control Dialog Box” on page 46.  
wtflush.exe \f - Flushes the cache and disables the Write Filter until the next system  
start. The Write Filter status icon is red.  
wtflush.exe \d - Flushes the cache and disables the Write Filter; the Write Filter  
remains disabled after the system start and must be enabled manually either through  
the Write Filter Control dialog box or through the command line. The Write Filter status  
icon remains red while disabled.  
wtflush.exe \e - Write filter enabled after the next system start. After enabling the Write  
Filter you must restart. You do not need to flush the cache first since the Write Filter is  
currently disabled. The Write Filter status icon is green when the Write Filter is  
enabled.  
Note  
Flush and disable (\fand \darguments) open and automatically close a  
DOS command window during the process. However, the flush could take up  
to several minutes to complete after the window closes. Because the DOS  
window does not stay open long enough to view the results, it is  
recommended that you open the Write Filter Control dialog box to determine  
if flushing has completed.  
Note  
The Write Filter status icon on the taskbar system tray turns red immediately  
when the cache flush operation is started, although the flush action can take  
up to several minutes to complete.  
Caution  
Do not attempt to flush the cache while the cache is currently being flushed.  
If you open an MS-DOS Prompt window (by entering commandin the Run text box),  
append “.exeto the wtflushcommand: wtflush.exe, wtflush.exe \f,  
wtflush.exe \d, and wtflush.exe \e.

Write Filter Enable and Write Filter Disable Desktop Icons  
For convenience, the Write Filter Enable and Write Filter Disable icons are present on the  
Administrator desktop. Depending on which icon you use, you can either enable or disable  
the Write Filter.  
Write Filter Enable Icon - Double-clicking this icon allows you to enable the Write  
Filter using the Write Filter Control dialog box. This utility is the equivalent of running  
the wtflush.exe \ecommand line option as described in “Write Filter Command  
Line Control” on page 44. The Write Filter is enabled and the system will automatically  
restart. You do not need to flush the cache first as the Write Filter is currently disabled.  
The Write Filter status icon in the taskbar system tray is green when the Write Filter is  
enabled.  
Write Filter Disable Icon - Double-clicking this icon allows you to disable the Write  
Filter. This utility is the equivalent of running the wtflush.exe \dcommand line  
option as described in “Write Filter Command Line Control” on page 44. This flushes  
the cache and disables the Write Filter. The Write Filter remains disabled after the  
system start and can only be enabled using the Write Filter Enable icon or through the  
command line as described in “Write Filter Command Line Control” on page 44. The  
Write Filter status icon in the taskbar system tray remains red while the Write Filter is  
disabled.  
Note  
A message will remain on the desktop until the Write Filter disable process is  
complete. Do not use the system during this time; the Thin Client will reboot  
automatically when it is finished disabling the Write Filter. When the disable  
action is complete, the Thin Client will boot with Write Filter disabled and be  
ready for permanent changes to flash.

NetXClean Utility  
NetXClean keeps extraneous information from being stored in flash memory. NetXClean is  
a service that runs in the background and operates on the flash memory only. NetXClean’s  
clean-up is triggered on either service startup or user log off. It performs the clean-up  
invisibly and no user input is necessary.  
NetXClean prevents garbage files from building up and filling the free space in the flash;  
for example, if a flush of the Write Filter cache puts junk in flash directories that must be  
kept clean or allows junk to continue being written to flash after the Write Filter cache is  
flushed (until a restart occurs). The NetXClean utility is particularly important when  
multiple users have log-on rights to a Thin Client, as memory space can be quickly used  
by locally stored profiles and temporary caching of information.  
Function Summary  
NetXClean’s TweakUI functions includes clearing:  
Run history at log-on  
Document history at log-on  
Find Files history at log-on  
Find Computer history at log-on  
Internet Explorer history at log-on  
Last User at log-on  
Selected Items Now  
NetXClean purges selected directories, files, and profiles. It uses a configuration file to  
determine which directories and files to purge, and what not to purge. To select different  
directories and files to purge, you must select them in the configuration file.  
Caution  
The selections are made by the manufacturer and should not be changed  
without manufacturer supervision.  
Regardless of the configuration file selections, NetXClean does not clean any of the  
following directories or their parent directories:  
Windows directory  
Windows System subdirectory  
Current directory in which the service is installed  
NetXClean will not delete the following profiles:  
Administrator  
All Users  
Default User  
The profile of the last user who logged on

Local Drives  
Administrators need to know the following information on local drives.  
Drive Z  
Drive Z is onboard volatile memory (Ms-ramdrive) of the Thin Client. Because drive Z is  
volatile memory, it is recommended that you do not use this drive to save data that you  
want to retain.  
For Ramdisk configuration information, refer to “RAMdisk” on page 37.  
For information about using the Z drive for roaming profiles, refer to “Domain Participation”  
Drive C and Flash  
Drive C is onboard non-volatile flash memory. It is recommended that you avoid writing to  
drive C. Writing to drive C reduces the size of the flash. If the flash size is reduced to  
under 3 MB, the Thin Client will become unstable.  
Caution  
If the free flash memory size is reduced to 2 MB, the Thin Client’s image will  
be irreparably damaged and it will be necessary for you to contact an  
authorized service center to repair the Thin Client. It is highly recommended  
that 3 MB of flash memory be left unused.  
The Write Filter (if ENABLED) protects the flash from damage and presents an error  
message if the cache is overwritten. However, if this message occurs you will be unable to  
flush the Write Filter cache and any Thin Client configuration changes still in cache will be  
lost.  
Note  
For information on NetXClean’s role in keeping the flash memory clean, refer  
Items that are written to the Write Filter cache (or directly to the flash if the Write Filter has  
been flushed) during normal operations include:  
Favorites  
Created connections  
Delete/edit connections  
Saving Files  
The Thin Client uses an embedded operating system with a fixed amount of flash memory.  
It is recommended that you save files that you want to keep on a server rather than on  
your Thin Client.  
Caution  
Be careful of application settings that write to the C drive, which resides in  
flash memory (in particular, those applications which by default write cache  
Download from Www.Somanuals.com. All Manuals Search And Download.  
       
50  
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. The default configuration  
settings mentioned in “User Log-on Accounts” on page 52 minimize writing to  
the C drive for factory-installed applications.  
Note  
For descriptions of the Write Filter and the need to flush the cache to  
permanently save configuration data, refer to “Write Filter” on page 41.  
Mapping Network Drives  
You can map network drives while logged on as either an administrator or a user. To keep  
the mappings after the Thin Client is restarted you must complete the following  
procedures:  
1. Select the Reconnect at logon check box.  
2. Flush the Write Filter cache during the current system session.  
Since a user log-on cannot flush the Write Filter cache, the mappings can be retained by  
logging off the user (do not shut down or restart the system) and logging back on as an  
administrator, and then flushing the cache.  
A remote home directory can also be assigned by using a user manager utility or by other  
means known to administrators.  
Domain Participation  
You can participate in domains by joining to a domain or by using roaming profiles.  
Joining a Domain  
As an administrator you can join a Thin Client to a domain through the Computer Name  
Changes dialog box. To open the Computer Name Changes dialog box, click Control  
Panel | System | Computer Name | Change.  
Caution  
Exercise caution when joining a domain as the profile downloaded at log-on  
could overflow the cache or flash memory.  
When joining a domain, the Write Filter should be disabled so that the domain information  
can be permanently stored on the Thin Client. The Write Filter should remain disabled  
through the next boot as information is written to the Thin Client on the boot after joining  
the domain. This is especially important when joining an Active Directory domain. For  
instructions on disabling and enabling the Write Filter, refer to “Write Filter” on page 41.  
To make the domain changes permanent, complete the following steps:  
1. Disable the Write Filter.  
2. Join the domain.  
3. Reboot the Thin Client.  
Download from Www.Somanuals.com. All Manuals Search And Download.  
     
51  
4. Enable the Write Filter.  
5. Reboot the Thin Client.  
Note  
If you use the Enable Desktop Icon to enable the Write Filter, the second  
reboot will happen automatically.  
Note  
By default, the NetXClean utility will purge all but specifically selected profiles  
on the system when the Thin Client starts up or when the user logs off. For  
information on how to ensure a new profile is not purged by the NetXClean  
Roaming Profiles  
Write roaming profiles to the C drive. The profiles must be limited in size and will not be  
retained when the Thin Client is restarted.  
Note  
For roaming profiles to work and be downloaded, there must be sufficient  
flash space available. In some cases it may be necessary to remove  
software components to free space for roaming profiles.  
WinPing Utility  
To open the WinPing window (see Figure 30), click Start | Run, type WinPingin the text  
field and clicking OK. The WinPing window is used to launch the Windows PING (Packet  
InterNet Groper) diagnostic utility and view the results from pinging.  
WinPing is a diagnostic tool familiar to administrators. It sends an echo request to a  
network host. The host parameter is either a valid host name or an IP address. If the host  
is operational and on the network, it responds to the echo request. The default is to send 5  
echo requests and then stop if no response is detected. WinPing sends one echo request  
per second, calculates round trip times and packet loss statistics, and displays a brief  
summary upon completion.

Figure 30 WinPing window  
WinPing is used to:  
Determine the status of the network and various hosts.  
Track and isolate hardware and software problems.  
Test, measure, and manage networks.  
Determine the IP address of a host if only the host name is known.  
Net and Tracert Utilities  
Net and Tracert utilities are available for administrative use. For more information on these  
utilities, go to: http://www.microsoft.com.  
User Log-on Accounts  
Administrators can create new users and configure user profiles.  
By default, a new user is only a member of the Users group and is not locked down. You,  
as the administrator, must select the attributes and profile settings for a new user.  
Caution  
By default, all application settings are set to cache to C drive. It is highly  
recommended that you cache to the Ramdisk Z drive (as is pre-set in the  
User and Administrator accounts) to avoid overflowing the Write Filter cache.  
Creating a New User Account  
New user accounts can be created by using the User Manager utility. You must be  
logged-on as an administrator to create new user accounts. You can create user accounts  
locally or remotely through VNC. However, due to local flash/disk space constraints, the  
number of additional users should be kept to a minimum.

53  
Caution  
Be sure to flush the Write Filter cache during the current system session in  
which a new account is created.  
To create a new user, complete the following procedures:  
1. Log-in as an administrator.  
2. Click Start | Settings | Control Panel | Administrative Tools and double-click the  
User Manager icon.

The New User dialog box opens.  
5. Type in the user name and password, and then select the attributes you want for the  
user.  
6. Click Create.  
7. Click Close.  
User Profiles  
Only an administrator can select the profile settings for a user. For example, new users  
cannot put themselves into the Administrators group, only the administrator can add a  
user to the Administrators group.  
Caution  
Because of the limited size of the flash memory, it is strongly recommended  
that other applications available to new and existing users be configured to  
prevent writing to the local file system. For the same reason, it is also  
recommended that extreme care be exercised when changing configuration  
settings of the factory-installed applications.  
To add a user to the Administrators group complete the following procedures:  
1. Log-in as an administrator.  
2. Click Start | Settings | Control Panel | Administrative Tools and double-click the  
User Manager icon.  
The Local Users and Groups window opens.  
3. In the Local Users and Groups window, select (highlight) the Users folder in the left

1. Click Start | Settings | Control Panel | System Properties to open the System  
Properties window.  
2. Click the Computer Name tab.  
3. Click Change... in the dialog box.  
4. Change the computer name in the text field provided.  
5. Click OK.  
Remote Administration and Firmware Upgrades  
Administrators need to know the following information on remote administration and  
firmware upgrades:  
Wyse Rapport Version 4.4  
Rapport is a full-featured remote administration tool set available from Wyse Technology.  
It accesses the Thin Client through the Rapport Agent, PXE, and VNC server utilities  
installed on the Thin Client. Rapport allows the Thin Client administration functions  
(including firmware upgrades) to be performed without requiring an administrator to visit  
the individual Thin Client sites.  
For specific information on using Rapport, consult the Rapport help documentation.  
Download from Www.Somanuals.com. All Manuals Search And Download.  
     
55  
For local custom fields that can be accessed by Rapport, refer to “Custom Fields” on  
Note  
When performing a mass distribution of a custom device image created with  
Rapport, the source device image will require unique preparation prior to  
creation and distribution. Please contact the device manufacturer for more  
detailed information.  
Add-on Modules  
To install an add-on module, an administrator must use the built-in Rapport Agent, PXE,  
and VNC server utilities of the Thin Client. Disable the Write Filter and enable the Write  
Filter as needed to save the changes.  
Firmware Upgrades  
Intel's Preboot Execution Environment (PXE) is a protocol that defines interaction  
between TCP/IP, DHCP and TFTP to enable a client to download a preboot environment  
from a server.  
The PXE client is installed on the Thin Client while the PXE server component is part of  
the Rapport Administrative Software suite.  
Note  
Citrix ICA auto update does not function for the ICA client installed on the  
Thin Client; updates are implemented through the standard firmware  
upgrade process. The Thin Client does not support upgrading using the  
Microsoft Windows update Web site.  
User Instructions on the First Boot Process After Loading a Standard Image  
(v2.2 or Earlier Only)  
If you are running version 2.2 or earlier, you must follow these important instructions when  
imaging the WintermTM 9000 Series Thin Clients with the standard XPe image  
downloaded from the Wyse Web site.  
Note  
When performing a mass distribution of a custom device image that has  
been created with Rapport, certain devices will require unique preparation  
prior to image creation and distribution. Please contact the device  
manufacturer for more detailed information.  
The WintermTM 9000 Series Thin Clients automatically run through the configuration steps  
on first boot after imaging. Failure to follow these instructions may result in system

corruption. You must not close the DOS window that is present during the process; the  
DOS window will close automatically.  
Event: The System Settings Change message may appear shortly after the first boot,  
depending on the specific hardware configuration of the Thin Client.  
The New Hardware Found message displays in the system tray (lower right hand  
corner of the screen).  
The System Settings Change message prompts for a system restart (see Figure 31).  
Figure 31 System Settings Change message  
Action: If this System Settings Change message appears, click No. Do not interrupt the  
Thin Client while it is automatically running through configuration and reboot.  
WinVNC  
Administrators Only - WinVNC Server is installed locally on the Thin Client. It allows a  
Thin Client to be operated/monitored (shadowed) from a remote machine on which VNC  
Viewer is installed. VNC is intended primarily for support and troubleshooting purposes.  
VNC Server starts automatically as a service at Thin Client startup. The service can be  
stopped/started by using the Services window (Start | Settings | Control Panel |  
Administrative Tools | Services).  
Note  
Be sure to flush the Write Filter during the current system session if you want  
to permanently save the state of the service.  
VNC Server Properties Settings  
To open the WinVNC: Current User Properties dialog box (see Figure 32), click Start |  
Programs | VNC User Settings, or double-click the WinVNC icon in the system tray of  
the administrator’s taskbar. The default password in this dialog box is Wyse.  
Caution  
The default password permits a remote administrator to configure or reset a  
Thin Client from a remote location rather than making a personal appearance  
at the Thin Client site. For security, it is highly recommended that the  
password be changed immediately upon receipt of the Thin Client.
