Cisco Cisco Virtualization Experience Client 2212 Administrator's Guide

Connections can be defined in persistent memory (with a statement reading enablelocal=yes in 
the wnos.ini file). These connections can be displayed as desktop icons only in Standalone mode 
with a Non-privileged user.

Only the connections defined in an INI file and containing an icon= clause will be displayed on 
the desktop (assuming there is adequate desktop space).

Connections can be displayed on the desktop without requiring a sign-on (when you define 
these connections in a wnos.ini file or when the wnos.ini file does not contain a SignOn=yes 
statement).

ICA Guidelines—Independent Computing Architecture (ICA) is a three-tier, server-based 
computing technology that separates the logic of an application from its user interface. The ICA 
client software installed on the zero client allows the user to interact with the application GUI, while 
all of the application processes are executed on the server. ICA connects to NT TSE, Windows 
Server 2003, or Windows Server 2008 Server hosts that have a Citrix MetaFrame server, Citrix 
Presentation server, or CDS installed. Load balancing is included. ICA browsing or DNS can be 
used to resolve the server name. For information on configuring ICA, refer to 

. For detailed information on the supported parameters (in the INI files) 

that you can use for ICA connections, refer to the Cisco Virtual Experience Client 2112/2212 WTOS 
INI Files Reference Guide.

The ICA server must be licensed from Citrix Systems, Inc. You must purchase enough client 
licenses to support the total concurrent zero client load placed on the Citrix server farm. A 
failure to connect when all client seats are occupied does not represent a failure of Cisco 
equipment. The ICA client software is installed on the zero client.

RDP Guideline—Remote Desktop Protocol (RDP), like ICA, is a network protocol that allows a 
zero client to communicate with the Terminal Server or Windows 2003/2008 Server with Terminal 
Services over the network. This protocol is based on the T.120 protocol suite, an international 
standard multi-channel conferencing protocol. For information on configuring RDP, refer to 

. For detailed information on the supported 

parameters (in the INI files) that you can use for RDP connections, refer to the Cisco Virtual 
Experience Client 2112/2212 WTOS INI Files Reference Guide.

Before you use the information in this section to configure your ICA session services, be sure you have 
read 

ICA session services can be made available on the network using either Windows 2003/ 2008 Server with 
Terminal Services and one of the following installed:

Citrix MetaFrame XP

Citrix Presentation Server

If PNAgent/PNLite-published application services are to be made available to the zero clients, refer 
to 

 when installing Citrix MetaFrame XP.

When using the instructions accompanying these products to install them and make sessions and 
applications available to the zero clients sharing the server environment, be aware of the following:
