Understanding Your Thin Client
Users and Groups
What is a User Account?
The term user account should not be confused with the actual User account that
is the default account upon log-in. For each person using the terminal, the
owner can create an individual account. Each user account created can have
certain rights or permissions as chosen by the Administrator account. The
Administrator account can create, delete, and edit each of the users' settings
whenever needed.
User Account
The User account is the account that will automatically log-in at every boot. It
is also the account that should be used for guests or any user what should be
prohibited from modifying the thin client or its local drive in any way. There is
no password on this account by default. The User account holder can change his
or her account picture and create, delete, or change their account password. The
user account cannot change their own account name or account type, nor can
they install or uninstall any software. They may, however, use software
installed by the Administrator account.

Understanding Your Thin Client | 9
Administrator Account
By default, the User account is automatically logged in. To bypass this, you can
hold <Shift> during the boot process or hold <Shift> and click Log Off, which
can be seen by selecting the right arrow next to the Shut Down button option.
NOTE: The default passwordfor the AdministratoraccountisAdministrator(case
sensitive).
Logging into the Administrator account should be very similar to the User account, with
some additional icons on the desktop. Unlike the User account(s), the Administrator
account can:
Install and uninstall hardware and software.
Create and delete user accounts on the terminal.
Create account passwords for user accounts on the terminal.
Change names, pictures, and passwords.
Change a user's account type to administrator account.
NOTE: The Administrator account cannot changeits own account type to a limited User
account type unless there is at least one other account with administrator-privileges on
the thin client. This ensures that thereis always at least one administrator-level account
on the thin client.

What is Devon IT Echo Management Console Dell Edition?
As more and more corporate networks switch to Thin Clients due to their low
power consumption, low cost, and productivity, many developers have
scrambled to create new and more efficient ways to centrally manage and
reconfigure thin client terminals. Echo is the latest in thin client management
software.
With the Echo virtual appliance, you can use broadcast and IP Range Walk to
discover the thin clients, then remotely reboot, add connections and settings, add
user profiles, shadow, clone settings, or even Re-Imaging some models.

File-Based Write Filter (FBWF)
What is Disk Management?
Disk Management is the management of your terminals internal local drive disk.
It is quite literally the brain of your unit and taking care of the unit's disk is the
best way to ensure the unit will perform for as long as possible. A carefully
preserved local drive will work more efficiently, last much longer, and perform
better overall. In addition, proper security techniques will greatly reduce the
chance of fatal error messages and/or accidental malicious software downloads.
Another definition of the word management literally refers to managing several
thin clients from an Administrator terminal. The Administrator terminal logs
into a secure Echo server and can manage multiple thin clients simultaneously.
Your terminal is designed with both management techniques in mind, and this
chapter explains the steps required to manage your terminal correctly. The
terminal's local drive disk is protected by a Write Filter, which acts like a barrier
between the internet and your actual local drive. The user can use this barrier to
protect and manage the terminal's actual local drive from unwanted changes.
The terminals can also be managed remotely from another terminal using the
Echo Thin Client Management Software. Both ideas are introduced in this
section.
Write Filters
A write filter allows the user to decide which files are saved to the local drive,
and which files or changes are discarded. Use the write filter to configure which
files are written to the disk permanently, and which files are only written to an
overlay in the memory. The write filter, when turned on, will make disk
changes like installing new hardware, upgrading internet browsers and plug-ins,
or isolating a virus to the terminal's memory, in an overlay. The changes are not
saved to the local drive. The next time the terminal is rebooted, the new
hardware is not installed, your browser or plug-in is not upgraded, and the virus
is gone. All of the changes are stored on a memory overlay and are erased on
reboot. Once the memory overlay is wiped clean, the original underlying image
remains unchanged, still in the state it was in since the last reboot. It is a good
practice to leave the filter turned on unless you are upgrading or installing new
hardware or software. After the installation is complete, it is recommended you
re-enable the write filter.

Understanding Your Thin Client | 13
All attacks on the terminal's security or unwanted changes can be thwarted by
simply rebooting the machine if the filter is turned on. Operating the machine
with the Filter turned off can be dangerous to the terminal and the important OS
files inside it.
Introduction to FBWF
The File-Based Write Filter, more commonly referred to as the FBWF, is a an
intelligent filtering system that allows you to protect specific volumes of your
local drive from write access, while simultaneously keeping less important files
like anti-virus databases or a user's Documents and Settings folder persistent.
The FBWF allows users to decide which directories are persistent and which are
transient. Persistent files are files that are not protected by the FBWF filter, and
all changes, good or bad, will survive after rebooting. Transient files are files
that are protected by the FBWF filter and all changes that are made to these files
are neglected and forgotten upon rebooting the terminal.
How Does FBWF Work?
When the FBWF is enabled, it makes your files secure from that instance.
Rebooting the terminal will revert your system immediately back to the state it
was in when you enabled it, like a restore point. As long as your FBWF is
enabled, it is in a safe state. It stays safe because it writes all changes made on
the system on an overlay in the RAM memory cache. An overlay can be
thought of as a protective layer over the disk. All changes made to the disk are
written on the transparent layer instead of the actual disk. When the terminal
looks for information on the disk, all upgrades and new installs can be found and
accessed because it is written on the overlay which is covering the disk.
However, once the terminal is rebooted, the memory cache is erased, and the
overlay is wiped clean, with no changes made. The system automatically
resumes from the same point it was at when you enabled the filter.
To install new hardware and software, or to upgrade any existing programs or
applications on your system, you will have to disable the FBWF. It is important
to re-enable the File-Based Write Filter as soon as the installation is complete so
you can protect your terminal from unnecessary disk writes. As long as you are
not installing or upgrading, it is necessary to leave the File-Based Write Filter in
an enabled state for correct performance. As long as it is enabled, your terminal
is safe from malicious network attacks or accidental uninstalls.

14 |Understanding Your Thin Client
Using the FBWF
The FBWF operates by providing a shadow write to the system RAM. When
enabled, any writes that are normally written to the storage media, are instead
redirected to the RAM overlay. During a reboot, this overlay is discarded so the
operating system remains in its original state. As its name implies, FBWF is
based on files. This means you can exclude certain files and directories from the
protection of the write filter. Any files that are in this list are ignored by FBWF
and subject to modification (or deletion) just as they normally would on any
standard Windows XP environment. The OptiPlex thin clients include a
management utility for configuring FBWF. The FBWF Manager utility can
only be accessed by Administrators.
To open the FBWF Manager , log-in as the administrator.
• Click Start-> All Programs-> FBWFGUI .
• This will open the FBWF Manager window.
By default, FBWF is enabled with basic exclusions set for the Persistent
Registry and Documents and Settings for all users. This means any changes
made under the C:\Documents and Settings folder, such as desktop icons, start
menu items, and browser favorites, will be written directly to the flash device
immediately and without overlay protection.
What is Persistence?
Persistence in its simplest definition is the term used to describe data on a local
drive or disk that exists and survives from session to session. Persistent data
will be secure after every reboot and every change made will be applied until
another user reconfigures your changes. If you do not have the File-Based
Write Filter installed on your terminal for protection, your local drive remains in
a Persistent state. All changes made to the desktop, program files, user settings
files, or important Windows system files are permanently stored on the drive or
disk. In the unfortunate event of a malicious network attack or virus, your files
may be harmed in the process if Persistence is left on. When the FBWF filter is
enabled and files can be protected, all changes made, including accidental virus
entries, are wiped upon reboot.

Installing Additional Software
You may install third party licensed software as long as there is adequate space
on the flash media.
To install additional software applications:
1 Log-in as an Administrator. Click Start->All Programs->FBWFGUI .
2 Temporarily disable the write filter by clicking the Disable FBWF
button, and press the Apply button.
3 Reboot the terminal.
4 Log-in again as Administrator and install the new software.

16 |Understanding Your Thin Client
5 After installation, verify the application is working as expected.
6 Launch the FBWF Manager and click the Enable FBWF button. Also,
make sure to re-enable the Basic Exclusions . For default exclusions,
this would mean selecting the buttons for Enabled Documents and
Settings for Everyone and the Enabled Persistent Registry .
7 Click Apply and Reboot the terminal one last time.

Understanding Your Thin Client | 17
Installing MUI Packs
You may install MUI (Multilingual User Interface) packs to enable the operating
system to support different languages and language settings on your terminal as
needed. The MUI pack installation file can not be located on the DOM, it must
be installed from an external drive or over the network due to disk size
limitations.
NOTE: Installing a MUI pack will reboot the system, so be sure to save and close all
programs beforestarting the process to avoid losing your work.
To install a MUI pack:
1. Log-in as an Administrator. Click Start->All Programs->FBWFGUI .
2. Temporarily disable the write filter by clicking the Disable FBWF
button, and press the Apply button.
3. Reboot the terminal.
4. Log back in as an Administrator.
5. Launch the MUI installer for the desired language.
6. Click on Run in the security warning screen.

18 |Understanding Your Thin Client
7. A command shell window will open noting the files being copied. Be
sure to leave it open.
8. A dialog box will open and keep track of the files as they are installed.
9. Once the installation is completed, the system will reboot. Make sure
to let the system reboot itself without interruption or the installation
process may be unsuccessful.
