If desired, you can customize the INI files to match the local environment using the instructions in the
Cisco Virtual Experience Client 2112/2212 WTOS INI Files Reference Guide. If you modify the INI files
to include icons and logos, be sure to place the images in the FTP server/wnos/ bitmap subdirectory.

Configuring Virtual Desktop Infrastructure Servers
When the zero client boots, it accesses the INI files from a Virtual Desktop Infrastructure (VDI) server.
VDI servers are available through DHCP vendor option 188 (see

The zero client communicates with a Virtual Desktop Broker server by the sysinit, signon, signoff, and
shutdown commands. When the zero client boots and successfully connects in a Virtual Desktop
environment, it sends the sysinit command to the Virtual Desktop Broker, which then sends back the
wnos.ini file (if a broker connection cannot be made, the zero client will attempt to connect to an FTP
or PNLite server). After the zero client successfully receives the wnos.ini from the Virtual Desktop
Broker, a sign-on window displays, prompting the user for username and password credentials. The zero
client then sends the signon command to the Virtual Desktop Broker with the username and password
as its parameter. If the sign-on is successful, the Virtual Desktop Broker server will send back the
{username}.ini file (if the sign-on is unsuccessful, the user is prompted again for username and
password credentials). The signoff command will be sent when a user disconnects from the connection.
The shutdown command will be sent when a user turns off the zero client power.

Configuring XenDesktop Support
XenDesktop is supported in WTOS without the need to use a Web browser. To connect to XenDesktop,
do not use the VDI Broker parameter. Instead, use the same parameter and configuration that is used
when connecting to a PNAgent/Lite server.

Configuring DHCP (DHCP Options)
Before you use the information in this section to configure your DHCP server, be sure you understand
and use the following guidelines:
and use the following guidelines:
•
General Guidelines—The DHCP service provides all zero clients on the network with their IP
addresses and related network information when the zero clients boot. DHCP also supplies the IP
address and directory path to the zero client software images and user profiles located on the file
servers.

address and directory path to the zero client software images and user profiles located on the file
servers.
Use of DHCP is recommended. However, if a DHCP server is not available, fixed IP addresses can
be assigned (this does, however, reduce the stateless functionality of the zero clients) and the fixed
IP addresses must be entered locally for each device using the zero client Network Setup dialog box
as described in
