Configuring RDP Session Services
Before you use the information in this section to configure your RDP session services, be
sure you have read "Configuring Session Services."
RDP session services can be made available on the network using any of the following:
• Windows 2000, 2003, or 2008 Server with Terminal Services installed
• Windows NT 4.0 Terminal Services (WTS) Edition
• Windows 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 (90-day) license on an individual device basis. Beyond
the temporary (90-day) license, you must purchase TSCALs and install them on the

• Wyse ThinOS version 4.2 and later supports an RDP connection with no encryption
(found in older versions of Microsoft NT4-TSE servers).
• Wyse ThinOS version 4.2 and later supports server browsing over Server Message
Block (SMB) when defining an RDP connection. SMB browsing restrictions mean that
the server desired may not be listed, in which case the user will need to know either the
name or IP address of the target server and enter that information into the text box (as
it will not appear in the pull-down list).
