5 Establishing a Server Environment
This section contains information on the network architecture and enterprise server
environment needed to provide network and session services enabling Wyse X class thin
computers network connection. It also includes information to help you to address
important considerations when configuring access to the server environment and when
configuring the services to be provided by the server environment.
Setting Up Access to the Enterprise Servers
There are five basic methods of access to the enterprise server environment available to
the thin computer. Except for Ethernet Direct, all of the access methods require that some
local settings be made on the thin computer. These local settings are retained and are
available for the next thin computer system start. Activating these local settings and the
defined connections can also be automated at thin computer system start.
Methods of access include:
• Ethernet Direct - This is a connection from the thin computer Ethernet port directly to
the enterprise intranet. No additional hardware is required. In this configuration all
network services may be used, including the enterprise DHCP server. A DHCP server
on the network can provide not only the thin computer IP address, but also the location
of the file server containing the software updates.
• Wireless Direct - A supported wireless adapter (or the optional internal wireless
feature) can be used to access the enterprise intranet. A wireless adapter uses
short-range wide-band radio to communicate with a wireless access point. Typically,
wireless access points are located at several locations in the enterprise within range of
the wireless adapters and directly connected to the enterprise intranet.
• PPPoE - Thin computer support for Point-to-Point Protocol over Ethernet (PPPoE) is
intended for devices which connect to the Internet directly from remote locations. The
New Connection Wizard can be used (available from Network Connections in the
Control Panel) to configure and invoke a PPPoE connection. Once connected, all
packets are through a PPP connection over Ethernet to the DSL modem. For more
information on the New Connection Wizard, refer to documentation on the Microsoft
Web site at:

• Dial-up Modem - A dial-up modem can be used with the thin computer to access a
dial-up server. The dial-up server must be a Microsoft Remote Access Server or
another server that supports industry-standard protocols. The dial-up server can
provide either of the following methods of access to the enterprise intranet:
• Direct access - An enterprise dial-up server directly connects to the enterprise
intranet.
• Indirect access - An Internet Service Provider (ISP) dial-up server simply provides
access to the Internet, from which the thin computer accesses an enterprise PPTP
VPN server that connects to the enterprise intranet.
