Establishing a Server Environment 23
Configuring ICA Session Services
Before you use the information in this section to configure your ICA session services, be
sure you have read "Configuring Session Services."
ICA session services can be made available on the network using either Windows 2000,
2003, or 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 thin clients, refer to "PNAgent/PNLite Installation Guidelines" when
installing Citrix MetaFrame XP.
When using the instructions accompanying these products to install them and make
sessions and applications available to the thin clients sharing the server environment, be
aware of the following:
If a Windows 2000, 2003, or 2008 Server is used, a Terminal Services Client Access
License (TSCAL) server must also reside somewhere accessible on the network. The
server will grant a temporary (120-day) license on an individual device basis. Beyond
the temporary (120-day) license, you must purchase TSCALs and install them on the
TSCAL server (you will not be able to make a connection without a temporary or
permanent license).
It is recommended that any ICA connection which traverses a Dial-up or WAN
connection have Lowband=yes set in the INI files or the Optimize for low speed link
option selected in the Connection Settings (ICA) dialog box.
If an ICA connection is created using the Connect Manager and the Host Names or
Application Name text box is left blank, a message appears prompting the user to
enter the IP Address or Server Name of the ICA server to which to connect.
An audio input port is available (Audio can be recorded).
PNAgent/PNLite Installation Guidelines
PNAgent/PNLite is a component of the Citrix XML publishing service. PNAgent/PNLite is
an ICA connection mode that enables the thin client to connect to applications available
(published) on an ICA server without having to configure connections for individual
published applications.
Use the following guidelines during installation:
MetaFrame XP - Installing MetaFrame XP supports XML publishing services. During
installation, a series of prompts appear for you to follow. When you are prompted to
install the XML Publishing Service, be aware that clicking Yes to this option allows you
to change the default port (80) used by the service.
Citrix Presentation Server - Installing Citrix Presentation Server supports XML
publishing services. During installation, a series of prompts appear for you to follow.
The port to be used for XML publishing services must be known for making appropriate
PNAgent/PNLite server location entries required by the operating mode (for related
information, refer to "Configuring DHCP," the Users Guide: Wyse ThinOSTM (for locally
configuring the thin client using the Network Setup dialog box), and the Reference Guide:
Wyse ThinOSTM INI Files). The thin client uses port 80 as the default port, but if a port
other than 80 is used, the port number must be specified explicitly with the PNAgent/
PNLite server location in the form IP:port or name:port, where :port is optional.
