Administrator Guide
• VNC Server — Upon successful thin client logon, the Windows VNC Server utility is automatically launched. VNC allows a thin client
desktop to be accessed remotely for administration and support. See Using TightVNC to Shadow a Thin Client.
Utilities Aected by Log O, Restart, and Shut Down
The following utilities are aected by logging o, restarting, and shutting down the thin client :
• File Based Write Filter cache — If you make changes to system conguration settings and want them to persist after a reboot, you
must ush the les of the File Based Write Filter cache during the current system session. Otherwise, the new settings will be lost
when the thin client is shut down or restarted. The File Based Write Filter cache contents are not lost when you simply log o and on
again as the same or dierent user; that is, you can ush the les of the File Based Write Filter cache after the new logon and still retain
the changes. For instructions on ushing, see Before Conguring Your Thin Clients. For detailed information about the File Based Write
Filter, see Using the File Based Write Filter (FBWF)
NOTE: A user cannot ush the les of the File Based Write Filter cache; this is a local or remote administrator function.
• NetXClean Utility — NetXClean is a clean-up utility that keeps extraneous information from being stored on the ash memory. Clean-
up is triggered automatically on restart, shut-down, or user log-o. If you want to keep certain prole congurations for example,
printers, be sure to congure NetXClean to refrain from cleaning up any number of explicitly declared proles. For details about
NetXClean, seeBefore Conguring Your Thin Clients and Understanding the NetXClean Utility.
• Power Management — A Monitor Saver turns o the video signal to the monitor, allowing the monitor to enter a power-saving mode
after a designated idle time. Power settings are available in Start > Control Panel > Power Options.
• Wake-on-LAN — This standard Windows Embedded Standard feature discovers all thin clients in your LAN, and enables you to wake
them up by clicking a button. This feature allows WDM software, for example, to perform image updates and remote administration
functions on devices that have been shut down or are on standby. To use this feature, the thin client power must remain on.
•
NOTE
: Wake on LAN feature will not work by default for laptop clients; you must enable the feature in the bios. In
addition, for a laptop client, only S3 mode is supported the S5 mode is not supported.
• Thin Client Time —After power o, clock time will not be lost as long as the power source remains on. Clock time will be lost if the
power source is o and a battery is not installed. The local time utility can be set to synchronize the thin client clock to a time server
automatically at a designated time, or manually.
NOTE
:
Correct time should be maintained as some applications require access to local thin client time. Use the Date and Time dialog
box Start > Control Panel > Date and Time or by clicking the time area in the taskbar and then clicking the Change date and
time settings link to edit the time and date as needed.
Using the File Based Write Filter (FBWF)
The File Based Write Filter provides a secure environment for thin client computing by protecting the thin client from undesired ash
memory writes ash memory is where the operating system and functional software components reside. By preventing excessive ash
write activity, the File Based Write Filter also extends the life of the thin client. It gives the appearance of read-write access to the ash by
employing a cache to intercept all ash writes and returning success to the process that requested the I/O.
The intercepted ash writes stored in cache are available as long as the thin client remains active but are lost when the thin client is
restarted or switched o. To preserve selected changes, the selected les of the cache can be transferred to the ash on demand by using
WDM software or manuallyby using Commit in the File Based Write Filter Control dialog box; alternatively, if the les aected by the
changes are not known, the changes can be made after disabling the File Based Write Filter using the File Based Write Filter Control
dialog box, and then re-enabling the File Based Write Filter, For more information, seeSetting the File Based Write Filter Controls.
The File Based Write Filter can be controlled either through the command line (fbwfmgr) or by double-clicking the File Based Write Filter
icon in the Administrator system tray. The File Based Write Filter can ush specied les to the ash from cache only up to the point when
the commit is performed; if more writes are performed on the les that have been ushed, then these les must be ushed/committed
again if the additional changes also need to be preserved.
