Working with the File Based Write Filter Utility
The File Based Write Filter provides a secure environment for thin client computing by
protecting the thin client from undesired flash memory writes. Changes made to the thin
client configurations are lost when the thin client is restarted unless the files of the File
Based Write Filter cache are flushed/committed during the current system session. Only
administrators can modify thin client configurations to persist after a thin client reboot.
1. Log on as an administrator (see "Logging On").
2. Disable the File Based Write Filter by double-clicking the FBWF Disable (red) icon on
the desktop (this will disable the filter and reboot the system).
3. If automatic logon to a user desktop is enabled, you must log off the user desktop and
log on as an administrator (as you did in step 1).
4. Configure the thin client as you want using the instructions in this guide.
5. After you complete your configurations, you must enable the File Based Write Filter by
double-clicking the FBWF Enable (green) icon on the desktop (this will enable the filter
and reboot the system). Your configurations on the thin client are now saved and they
will persist after a thin client reboot.
For general information about the File Based Write Filter, see "Using the File Based Write
Filter (FBWF)."
Working with the NetXClean Utility
NetXClean is a clean-up utility that keeps extraneous information from being stored on the
local disk. If you want to keep certain profile configurations (for example, printers and
other peripherals), be sure to configure NetXClean to refrain from cleaning up any number
of the explicitly declared profiles you want.
For general information about NetXClean, see "Understanding the NetXClean Utility."
For detailed instructions on using NetXClean, see Wyse Knowledge Base Solution
#10621 (go to the Wyse Knowledge Base at http://www.wyse.com/kb
and search for

Connecting to a Printer
To connect a parallel printer to your thin client through a USB port, you will need a
USB-to-printer adapter cable (not included). Before use, you may need to install the driver
for the printer by following the printer driver installation instructions. For information on
connecting to printers, see "Configuring Devices and Printers."
Connecting to a Monitor
Depending on your thin client hardware, connections to monitors can be made using
either a VGA (analog) monitor port or a DVI (digital) monitor port and the proper Wyse
monitor cables/splitters. For information on configuring dual display settings, see
"Configuring Dual Monitor Display."
TIP: For dual-monitor supported thin clients using a DVI to DVI/VGA splitter with VGA and
DVI monitors at the same time, note that the VGA monitor will be the primary monitor.
