Carl,

 

Excellent post. I think this covers many of the issues we are seeing with
these thin client devices. We tested

some of the embedded XP devices in and have not been totally satisfied. The
local printing problem and inability

to install programs locally has led us to recommend installing PC's for
their needs.

Subject: [THIN] Re: Recommendations for Thin client devices

 

Here is my rant against thin clients. I produced this list based on the
perspective of somebody that has to manage and support the Presentation
Server infrastructure.

 

Thin Clients vs. PCs

The ideal end-user device, where full Citrix functionality is possible with
maximum flexibility and minimum administrative burden, is a Windows based PC
(Windows XP or above preferred). The following is key functionality of a
Windows based PC client device when used with a Citrix Presentation Server
architecture:

*         Full ICA Functionality including SpeedScreen Multimedia
Acceleration. New ICA functionality is achieved by simply upgrading the ICA
client to the latest version.

*         Full support of client printing with the Universal Print Driver on
the Citrix Presentation Servers. This eliminates needing to install print
drivers on the Citrix Presentation Servers and eliminates needing to
configure Citrix Policies or complicated scripting to map printers at logon.
Essentially, all printing functionality is offloaded to the client.

*         Flexibility to run local applications if it is not cost
advantageous to publish an application from Citrix Presentation Server. When
a client device runs both local apps and Citrix published apps, Choice
Solutions refers to the device as a hybrid client. The Citrix PNAgent ICA
Client provides seamless integration of Citrix published applications into
the PC's Start Menu and Desktop meaning that users use one method to launch
both local applications and Citrix published applications.

Thin Clients are advantageous for shop floors, where moving parts are more
susceptible to failure, and kiosks, where a minimal device improves
security. For other cases, thin clients might seem attractive for their
lower initial cost but there are several reasons to reconsider using them:

*         The ICA client running on a thin client is not fully featured. 

The only thin client OS that supports full ICA client functionality is
Embedded XP. Some features missing from other thin clients are Universal
Print Driver v3 (the new one in Citrix Presentation Server 4) and
SpeedScreen Multimedia Acceleration (using client resources to play media
files and streaming media resulting in user experience identical to playing
the media on the PC). 

*         Most thin clients lack client printing requiring network printers
to be configured on the Citrix Presentation Servers.

Client printing is ideal because the new Universal Print Driver (UPD) does
not require print drivers to be loaded on the Citrix Presentation Servers.
Without client printing, network printers are required to be mapped within
an ICA session. This consists of mapping the printer (using a script or
Citrix Policies) and loading print drivers on the Presentation Servers.
Network printers complicate the printing architecture of a Citrix
Presentation Server architecture. 

If you must implement network printers for thin client printing support,
ensure that the drivers installed on the Citrix Presentation Servers are all
included with Windows. Do NOT install drivers downloaded from the printer
vendor's website. Also, if installing Windows 2003 x64 on the Presentation
Servers, ensure that all print drivers are 64-bit.

Thin clients with the Embedded XP OS do support client printers. However,
most print drivers are not included with the Embedded XP OS requiring the
administrator to install the drivers on the thin client. Also, not all
drivers will successfully install on the Embedded XP thin client due to
functionality removed from the Embedded XP OS to allow it to fit on the
flash drive.

*         Most thin clients do not support locally installed applications.

It is rare to see a Citrix Presentation Server implementation where all
applications are published from Citrix Presentation Servers. The primary
reason to not install an application on Presentation Server is lack of
tangible benefits as compared to the cost of integrating the application.
Remember, every application installed on a Citrix Presentation Server farm
must go through an extensive testing, configuration, stress loading, and
documentation process and it is not cost effective to send an application
used by a small number of users through this process.

Embedded XP thin clients do support locally installed applications with
several caveats. The flash drive in these thin clients is typically 512 MB
or 1 GB in size resulting in an inability to install large applications.
Larger flash drives also increase the price of the thin client putting it in
the realm of PC pricing. 

While the Embedded XP OS is based on Windows XP, it is a subset of that OS.
Some applications might require more of Windows XP than is typically
available on an Embedded XP thin client.

*         Thin clients possess sub-par graphics capability as compared to
today's low end PCs.

One method for reducing costs in thin clients is to skimp on the graphics.
This results in smaller screen resolutions, lower color depth, and
noticeably slower screen updates. Before buying a particular thin client,
let some users try it to determine if the graphics performance is
acceptable.

*         PNAgent will only run on Embedded XP thin clients.

PNAgent is the preferred method of accessing published applications from a
client device because it is centrally administered and provides seamless
integration with the local desktop (shortcuts are placed on the Start Menu,
Desktop, and in the system tray). PNAgent can be installed and used from
Embedded XP thin clients only.

For other types of thin clients, consider publishing a desktop with the
common Start Menu program groups hidden (use Group Policy to do this) and
run PNAgent within that published desktop. PNAgent will display or not
display application shortcuts within the published desktop based on a user's
group membership. While this is easy to setup, it does provide an additional
access method that must be maintained.

*         Centralized management of thin clients is proprietary to the thin
client vendor.

Every thin client vendor offers a software solution for management of their
thin clients. This management software typically only works with a specific
vendor's thin clients. Also, the management software does not integrate with
other PC management software, like Microsoft SMS, so you must maintain an
additional client device management infrastructure.

*         Embedded XP thin clients need to be managed just like a PC.

Since most PC functionality is built into Embedded XP thin clients,
including the ability to catch a virus, these thin clients should be managed
just like a PC, resulting in increased management costs for this particular
class of thin clients. Some Embedded XP thin client vendors offer antivirus
and firewall protection for their Embedded XP thin clients.

A common method of managing Embedded XP thin clients is to join it to a
Windows domain so the thin client can receive group policies, login scripts,
mapped printers, etc. Another advantage of joining the domain is that the
credentials a user uses to log in to the thin client can be passed through
the PNAgent client eliminating the second logon.

However, the Write Filter, which prevents changes to the flash disk,
included with these thin clients prevents the thin clients from storing
changed domain workstation passwords. Either the Write Filter must be
disabled or the password changing must be disabled. If the Write Filter is
disabled, there is potential for the user to break the system requiring a
thin client image to be reloaded. Preventing the workstation password from
changing results in reduced network security. The DisablePasswordChange
registry key will prevent the thin client from changing its domain password.

*         All upgrades and support are offered only by the thin client
vendor.

Citrix Support cannot provide thin client specific assistance. If an issue
is discovered on a thin client that cannot be reproduced on a PC, the thin
client vendor must be contacted for support.

As Citrix releases new versions of the ICA Clients, you must wait for the
thin client vendor to release an image that includes the newer versions.
This could result in a discrepancy in features and bug fixes between the PCs
and the thin clients.

I read this recently. A very good discussion of the relevance of these

devices vs. cheap PC's.

only thin client OS that supports full <st1:City w:st="on"><st1:place \
w:st="on">ICA</st1:place></st1:City> client functionality is Embedded XP. Some \
features missing from other thin clients are Universal Print Driver v3 (the new one \

client resources to play media files and streaming media resulting in user experience \
identical to playing the media on the PC). <o:p></o:p></span></font></p>

Citrix Presentation Servers.<o:p></o:p></span></b></p>

<p class=CSNormal3><font size=2 face=Arial><span style='font-size:11.0pt'>Client
printing is ideal because the new Universal Print Driver (UPD) does not require
print drivers to be loaded on the Citrix Presentation Servers. Without client
printing, network printers are required to be mapped within an <st1:City \
w:st="on"><st1:place  w:st="on">ICA</st1:place></st1:City> session. This consists of \
mapping the printer (using a script or Citrix Policies) and loading print drivers on \
the Presentation Servers. Network printers complicate the printing architecture of
a Citrix Presentation Server architecture. <o:p></o:p></span></font></p>

<p class=CSNormal3><font size=2 face=Arial><span style='font-size:11.0pt'>If
you must implement network printers for thin client printing support, ensure
that the drivers installed on the Citrix Presentation Servers are all included
with Windows. Do NOT install drivers downloaded from the printer vendor&#8217;s
website. Also, if installing Windows 2003 x64 on the Presentation Servers,
ensure that all print drivers are 64-bit.<o:p></o:p></span></font></p>

<p class=CSNormal3><font size=2 face=Arial><span style='font-size:11.0pt'>Thin
clients with the Embedded XP OS do support client printers. However, most print
drivers are not included with the Embedded XP OS requiring the administrator to
install the drivers on the thin client. Also, not all drivers will successfully
install on the Embedded XP thin client due to functionality removed from the
Embedded XP OS to allow it to fit on the flash drive.<o:p></o:p></span></font></p>

<p class=CSNormal3><font size=2 face=Arial><span style='font-size:11.0pt'>It is
rare to see a Citrix Presentation Server implementation where <i><span
style='font-style:italic'>all</span></i> applications are published from Citrix
Presentation Servers. The primary reason to not install an application on
Presentation Server is lack of tangible benefits as compared to the cost of
integrating the application. Remember, every application installed on a Citrix
Presentation Server farm must go through an extensive testing, configuration,
stress loading, and documentation process and it is not cost effective to send
an application used by a small number of users through this \
process.<o:p></o:p></span></font></p>

<p class=CSNormal3><font size=2 face=Arial><span style='font-size:11.0pt'>Embedded
XP thin clients do support locally installed applications with several caveats.
The flash drive in these thin clients is typically 512 MB or 1 GB in size
resulting in an inability to install large applications. Larger flash drives
also increase the price of the thin client putting it in the realm of PC
pricing. <o:p></o:p></span></font></p>

<p class=CSNormal3><font size=2 face=Arial><span style='font-size:11.0pt'>While
the Embedded XP OS is based on Windows XP, it is a subset of that OS. Some \
applications might require more of Windows XP than is typically available on an \
Embedded XP thin client.<o:p></o:p></span></font></p>

<p class=CSNormal3><font size=2 face=Arial><span style='font-size:11.0pt'>One
method for reducing costs in thin clients is to skimp on the graphics. This
results in smaller screen resolutions, lower color depth, and noticeably slower
screen updates. Before buying a particular thin client, let some users try it
to determine if the graphics performance is acceptable.<o:p></o:p></span></font></p>

<p class=CSNormal3><font size=2 face=Arial><span style='font-size:11.0pt'>PNAgent
is the preferred method of accessing published applications from a client
device because it is centrally administered and provides seamless integration
with the local desktop (shortcuts are placed on the Start Menu, Desktop, and in
the system tray). PNAgent can be installed and used from Embedded XP thin
clients only.<o:p></o:p></span></font></p>

<p class=CSNormal3><font size=2 face=Arial><span style='font-size:11.0pt'>For
other types of thin clients, consider publishing a desktop with the common
Start Menu program groups hidden (use Group Policy to do this) and run PNAgent
within that published desktop. PNAgent will display or not display application
shortcuts within the published desktop based on a user&#8217;s group
membership. While this is easy to setup, it does provide an additional access
method that must be maintained.<o:p></o:p></span></font></p>

<p class=CSNormal3><font size=2 face=Arial><span style='font-size:11.0pt'>Every
thin client vendor offers a software solution for management of their thin
clients. This management software typically only works with a specific
vendor&#8217;s thin clients. Also, the management software does not integrate
with other PC management software, like Microsoft SMS, so you must maintain an
additional client device management infrastructure.<o:p></o:p></span></font></p>

PC.<o:p></o:p></span></b></p>

<p class=CSNormal3><font size=2 face=Arial><span style='font-size:11.0pt'>Since
most PC functionality is built into Embedded XP thin clients, including the
ability to catch a virus, these thin clients should be managed just like a PC,
resulting in increased management costs for this particular class of thin
clients. Some Embedded XP thin client vendors offer antivirus and firewall
protection for their Embedded XP thin clients.<o:p></o:p></span></font></p>

<p class=CSNormal3><font size=2 face=Arial><span style='font-size:11.0pt'>A
common method of managing Embedded XP thin clients is to join it to a Windows
domain so the thin client can receive group policies, login scripts, mapped
printers, etc. Another advantage of joining the domain is that the credentials
a user uses to log in to the thin client can be passed through the PNAgent
client eliminating the second logon.<o:p></o:p></span></font></p>

<p class=CSNormal3><font size=2 face=Arial><span style='font-size:11.0pt'>However,
the Write Filter, which prevents changes to the flash disk, included with these
thin clients prevents the thin clients from storing changed domain workstation
passwords. Either the Write Filter must be disabled or the password changing
must be disabled. If the Write Filter is disabled, there is potential for the
user to break the system requiring a thin client image to be reloaded.
Preventing the workstation password from changing results in reduced network
security. The <b><span style='font-weight:bold'>DisablePasswordChange</span></b>
registry key will prevent the thin client from changing its domain \
password.<o:p></o:p></span></font></p>

Support cannot provide thin client specific assistance. If an issue is
discovered on a thin client that cannot be reproduced on a PC, the thin client
vendor must be contacted for support.<o:p></o:p></span></font></p>

<p class=CSNormal3><font size=2 face=Arial><span style='font-size:11.0pt'>As
Citrix releases new versions of the ICA Clients, you must wait for the thin
client vendor to release an image that includes the newer versions. This could
result in a discrepancy in features and bug fixes between the PCs and the thin
clients. <o:p></o:p></span></font></p>
