Using TightVNC to Shadow a Thin Client
TightVNC Server is installed locally on the thin client. It allows a thin client to be
shadowed/operated/monitored from a remote machine on which TightVNC Viewer is
installed (TightVNC Viewer is available from the TightVNC Web site; it is also included as
a component of Wyse Device Manager software and must be installed on the remote/
shadowing machine before use).
TightVNC (Server and Viewer) allows a remote administrator to configure or reset a thin
client from a remote location rather than making a personal appearance at the thin client
site (VNC is intended primarily for support and troubleshooting purposes). TightVNC
Server starts automatically as a service at thin client startup. The service can also be
stopped and started by using the Services window (opened by clicking Start > Control
Panel > Administrative Tools > Services).
TIP: If you want to permanently save the state of the service, be sure to flush the files of
the File Based Write Filter during the current system session.
Before an administrator on a remote machine (on which TightVNC Viewer is installed) can
access a thin client (with TightVNC Server) the administrator must know the:
• IP Address (or valid DNS name) of the thin client that is to be shadowed/operated/
monitored (see
"Viewing Wyse Client Information"). To obtain the IP address of an
administrator thin client, hover the mouse arrow over the VNC icon in the system tray
of the Administrator taskbar.
• Primary Password of the thin client (default password is Wyse) that is to be shadowed/
operated/monitored (see
"Configuring TightVNC Server Properties").
To shadow a thin client from a remote machine:
1. Open the New Tight VNC Connection dialog box (for example, Start > All Programs
> TightVNC > TightVNC Viewer).
2. Enter the IP address or valid DNS name of the thin client that is to be shadowed/
operated/monitored (you can also set other options using the command buttons).
3. Click OK to open the VNC Authentication dialog box.
4. Enter the Password of the thin client that is to be shadowed (this is the Primary
Password of the thin client that is to be shadowed - default password is Wyse) and
click OK. The thin client that is to be shadowed/operated/monitored will be displayed
for the administrator in a separate window on the remote machine. Use the mouse and
keyboard on the remote machine to operate the thin client just as you would if you
were operating it locally.
