Write filters
Write filters provide a secure environment and can extend the life of your Digital Signage Players by protecting it from unauthorized and excessive writes to the storage device. Write data is intercepted by the write filter and cached in the RAM drive, and as a result, lost after the next reboot. There are two different types of write filters available:
Enhanced Write Filter (EWF)—Protects the entire storage device from writes
●
File-Based Write Filter (FBWF)—Allows you to specify files or folders to be excluded from
●
interception by the write filter
Only one write filter can be selected and active at one time. To save permanent configurations to the storage device, the write filter must be temporarily disabled.
CAUTION: Ensure that the write filter is enabled after committing necessary configurations to the
thin client flash drive. During normal operation of the thin client, the write filter must be enabled. Also ensure that Page File is not enabled on thin clients with flash memory storage. Failure to follow these required actions can void the warranty of the flash storage device. In the event of damage to the flash storage device due to operation with a disabled write filter or enabled Page File, the damage will not be covered by HP warranty.

Local drives

IMPORTANT: The write filter must be disabled for any configurations to be made permanent. See Write filters on page 2 for more information.
The following local drives are configured on the Digital Signage Player by default:
Drive C (storage device)—This is where the operating system and software are installed. Writes
●
to this drive can be limited or restricted entirely by using a write filter.
CAUTION: HP recommends that you do not allow the available free space on the storage
device to drop below 10% of the flash size. If the available free space on the storage device drops below 15 MB, the Digital Signage Player can become unstable.
Drive Z (RAM drive)—This is a virtual drive that is created from the system's physical RAM. This
●
drive will look and behave like a standard fixed disk drive, but it is created at system startup and destroyed at system shutdown. Therefore, HP recommends that you do not store information or data on this virtual disk drive.
You can use the HP RAMDisk Manager utility to configure the size of Drive Z. For more information, see
HP RAMDisk Manager on page 8.
Local drives 5

Configuring logon settings

IMPORTANT: The write filter must be disabled for any configurations to be made permanent. See Write filters on page 2 for more information.
For a user account, the factory-default user name and password are both User.
●
For an administrator account, the factory-default user name and password are both
●
Administrator.
For security purposes, HP recommends that you change the passwords from their default
●
values. An administrator can change passwords by pressing Ctrl+Alt+Del and then clicking Change a password.
NOTE: You cannot change the password while logged on as a user.
Passwords are case sensitive.
●
Alternatively, the Digital Signage Player can be configured to log on to a specific user account automatically. To configure automatic logon:
1. Click Start > Control Panel > HP Logon Manager.
2. In the Windows Logon Configuration dialog box, check the Enable Autologon box, type the
account credentials and domain name, and then click OK.
The configured account will be logged on to automatically during system startup.
TIP: To log on as a different user or as an administrator when automatic logon is enabled, simply
log off the current account to return to the Windows logon screen.

Configuring the system date and time settings

IMPORTANT: The write filter must be disabled for any configurations to be made permanent. See Write filters on page 2 for more information.
You can use the Date and Time utility in the Control Panel to set the system date and time manually or to configure the system to synchronize the date and time with an Internet server periodically.
TIP: You can also access this utility by clicking the clock in the Windows notification area and then
clicking Change time and date settings or by right-clicking the clock and selecting Adjust date/time from the menu.
If you want to configure the system to synchronize the date and time with an Internet server, you will also need to enable the Windows Time service, which is disabled by default. To do this, follow these steps:
1. Click Start > Control Panel > Administrative Tools.
2. Double-click Services.
3. Double-click the Windows Time service to access its settings. You can start the service manually

3 Software

Microsoft Remote Desktop Protocol

Make Microsoft Remote Desktop Protocol (RDP) available on the network using Microsoft Terminal Services on a Windows server. Use the Remote Desktop Connection (RDC) utility to establish a connection to a Windows terminal server or to access remote applications using Microsoft RDP.
To open the RDC utility:
Click Start > All Programs > Accessories > Remote Desktop Connection.
▲
NOTE: If a Windows server is used, a Terminal Services Client Access Licenses (TSCAL) server
must also reside somewhere on the network. A Client Access License (CAL) permits a client to use the services provided by the Windows server. The server grants temporary licenses (on an individual device basis) that are good for 90 days. Beyond that, TSCALs must be purchased and installed on the TSCAL server. A client cannot make a connection without a temporary or permanent license.

8 Chapter 4 Administration tools

HP ThinState

HP ThinState can be used to capture an HP Digital Signage Player image that can then be deployed to another HP Digital Signage Player of identical model and hardware.
NOTE: HP ThinState now uses ibrpe.exe for imaging. Any storage devices previously created
containing ibr.exe can no longer be used.
To perform an HP ThinState capture:
1. On the Digital Signage Player you are capturing the image from, make sure the first boot device
in the BIOS is set to USB.
2. Disable the write filter.
3. Insert a storage device that is greater in size than the onboard storage device.
4. Click Start > Control Panel > HP ThinState Capture.
5. Follow the on-screen instructions.
6. The HP ThinState Capture tool opens a blue screen. Follow the on-screen instructions.
Use the storage device to deploy the captured image to another HP Digital Signage Player of the exact same model and hardware.
NOTE: With HP ThinState Capture, you might be able to capture the image from a larger flash and
deploy it to a smaller flash, depending on the size of the captured image.
To perform an HP ThinState deployment:
1. On the Digital Signage Player you are deploying the image to, make sure the first boot device in
the BIOS is set to USB.
2. Insert the storage device that contains the captured image, and then restart the computer.
3. Follow the on-screen instructions.
After you remove the storage device and cycle power to the system, the image will unbundle. Do not interrupt or cycle power to the unit during this process.

HP Velocity
