About Configuring Session Services

Thin-client session services are made available by servers hosting Citrix ICA and

Microsoft RDP software products.

Note

A browser must be available through one of the session services to access

any on-line help documentation for users.

Be aware of the following connection information:

• There can be more connections than desktop space to display them.

• 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 Stand-alone 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 (only if there is enough desktop space).

• Connections can be displayed on the desktop without sign-on (when you define these

connections in a wnos.ini file or when the wnos.ini file does not contain a signon=1

statement).

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 thin 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 2003 server, or Windows 2000 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 "Configuring ICA Session Services."

Note

The ICA server must be licensed from Citrix Systems, Inc. You must

purchase enough client licenses to support the total concurrent thin client

load placed on the Citrix server farm. A failure to connect when all client

seats are occupied does not represent a failure of Wyse equipment. The ICA

client software is installed on the thin client.

Remote Desktop Protocol (RDP), like ICA, is a network protocol that allows a thin client to

communicate with the Terminal Server or Windows 2000/2003 Server with Terminal

Services over the network. This protocol is based on the T.120 protocol suite, an

international standard multi-channel conferencing protocol. The thin client supports both

RDP version 4.x and version 5.x.

For information on configuring RDP, refer to "Configuring RDP Session Services."
