Troubleshooting firmware corruption If the client beeps two times after it is powered on or does not appear to boot, then the device firmware may be corrupt. It is possible to resolve this by downloading the client image from http://www.hp.com, copying the image to a removable USB flash drive, and then booting the client from that flash drive. Reimaging client device firmware 1. Download the image from http://www.hp.com. 2. Unpack the image to the path C:\USBBoot. 3. Format a USB flash drive. 4. Copy all the files from C:\USBBoot to the root of the USB flash drive. 5. Power off the client. 6. Insert the USB flash drive into the client. 7. Power on the client. The client will boot to the USB flash drive. 8. Follow the on-screen instructions to reimage the client. 9. When the reimage process completes, remove the USB flash drive and press Enter. Troubleshooting serial or parallel printer configuration Before configuring printer ports, obtain the printer's baud rate from the printer's documentation. If you do not have that documentation, find the baud rate by completing the following: 1. Turn the printer on while pressing and holding the Feed button. 2. Release the Feed button after a few seconds. The printer will enter a self-test mode and print out the required information. TIP: You might need to turn the printer off to cancel the test mode or press Feed again to print a diagnostic page. NOTE: Most serial printers will print a diagnostic page when you perform this operation. If your printer will not print the diagnostic page, see the printer's documentation. To enter the printer's baud rate: 1. Using the Profile Editor under Registry, select root/printer-mapping-mgr/{UUID}/BaudRate. 2. Enter your printer's baud rate. NOTE: The UUID will match the UUID of the printer in root/printer. Look there and match the printer with the UUID in the root/printer-mapping-mgr. 3. Click Save. 4. Right-click the UUID, and then click Apply Changes. Troubleshooting Citrix password expiration If users are not being prompted to change expired Citrix passwords, then make sure the XenApp Services site (PNAgent site) has the Prompt authentication method set to allow users to change expired passwords. If you allow users to change their passwords by connecting directly to the domain Troubleshooting firmware corruption 31

Troubleshooting firmware corruption

If the client beeps two times after it is powered on or does not appear to boot, then the device

firmware may be corrupt. It is possible to resolve this by downloading the client image from

http://www.hp.com

, copying the image to a removable USB flash drive, and then booting the client

from that flash drive.

Reimaging client device firmware

Download the image from

http://www.hp.com

Unpack the image to the path

C:\USBBoot

Format a USB flash drive.

Copy all the files from

C:\USBBoot

to the root of the USB flash drive.

Power off the client.

Insert the USB flash drive into the client.

Power on the client. The client will boot to the USB flash drive.

Follow the on-screen instructions to reimage the client.

When the reimage process completes, remove the USB flash drive and press

Troubleshooting serial or parallel printer configuration

Before configuring printer ports, obtain the printer's baud rate from the printer's documentation. If you

do not have that documentation, find the baud rate by completing the following:

Turn the printer on while pressing and holding the

button.

Release the

Feed

button after a few seconds. The printer will enter a self-test mode and print out

the required information.

TIP:

You might need to turn the printer off to cancel the test mode or press

Feed

again to print a

diagnostic page.

NOTE:

Most serial printers will print a diagnostic page when you perform this operation. If your

printer will not print the diagnostic page, see the printer's documentation.

To enter the printer's baud rate:

Using the

Profile Editor

under

Registry

, select

root/printer-mapping-mgr/{UUID}/BaudRate

Enter your printer's baud rate.

NOTE:

The UUID will match the UUID of the printer in

root/printer

. Look there and match the

printer with the UUID in the

root/printer-mapping-mgr

Click

Save

Right-click the UUID, and then click
