Known Issues

Connection issues occur with View 6.2.2 and Citrix Netscaler

Zero clients may fail to authenticate with a View 6.2.2 connection server via a Citrix Netscaler load balancer when the load balancer is configured for SSL offloading mode. When the error occurs, the message ‘View Connection Server communication error’ is shown, or the zero client may reboot. (50735) Workaround: Configure the Netscaler load balancer to use SSL bridging instead of SSL offloading.

Security scanners may report zero client to be susceptible to CVE-2004-0230

Security scanners may report that the zero client is susceptible to CVE-2004-0230. This CVE exists in TCP stacks in devices that implement the Border Gateway Protocol. While this is a significant issue for routers that implement the Border Gateway Protocol, it is not a significant issue for zero clients. (45883)

Zero clients do not support automated smart card login to RDSH sessions

Zero clients fail the automated smart card login to VMware View Windows 2012 RDSH sessions because Windows 2012 sends an unexpected smart card control message to the zero client. (43869)

Incorrect Swiss-French keyboard mapping

Some accent characters on the Swiss-French keyboard may be incorrect in the zero client On-Screen Display (OSD), depending on the order in which the keys are held and released. (43050)

Zero client crashes under severe network impairment

Zero client may occasionally crash when the connection to the host is put under severe network impairment and video content is changing. (42570)

Zero client fails to resolve FQDN with a label that starts or ends with an underscore

Zero client will not resolve an FQDN that begins or ends with the underscore character (for example, _myhost.teradici.local). (40824)

Restrict Proximity Card setting does not work with VMware Horizon RDSH

The Restrict Proximity Card setting does not work with VMware Horizon RDSH sessions when set to disabled. (40754)

Smart card removal causes zero client to restart

Removing a smart card from a reader during a PCoIP session while the smart card is being accessed may cause the zero client to restart. (40729)

Tapping RFIDeas reader to end a session starts another PCoIP session

When the card belonging to the current user is tapped on a RFIDeas proximity card reader connected to the front USB ports of an Atrust w100 zero client to end a OneSign-brokered PCoIP session, the zero client may immediately start another PCoIP session for that user. (36515) Workaround: Connect the RFIDeas reader to the rear USB ports.

Host cannot access Promethean electronic whiteboard

The Promethean electronic whiteboard is not accessible by the PCoIP host when connected to a zero client. (36497)

Manual IPv6 gateway address is overwritten on reset

Although the IPv6 Gateway address is displayed as an editable field on the zero client Administrative Web Interface (AWI), changes to this field are not respected by the zero client firmware. Instead, the IPv6 gateway is determined using IPv6 Router Advertisement. (34901)

Configuring a zero client in IPv6 mode to manual addresses and setting the IPv6 Manual Address to the same value as the Link Local Address will make the zero client Administrative Web Interface (AWI) unreachable. (33783) Workaround: Use the On-Screen Display (OSD) to reconfigure the IPv6 address settings.

Wake-on-USB fails with Bloomberg keyboard when Auto Power-Off Timeout is set

If using a Bloomberg keyboard and Auto Power-Off Timeout is set, Wake-on-USB may fail if the zero client is put to sleep by using the power button. (30928)

Elo Touch monitor may lose calibration in OSD after used in bridged mode with certain Elo Multi-Touch drivers

An Elo Touch monitor connected to a zero client may lose its calibration settings and be unsable in the On-Screen Display (OSD) when the zero client connects to a PCoIP host running certain versions of the Elo Multi-Touch driver, and when the monitor is calibrated using Elo Multi-Touch driver on the host. (30150) Workaround: Use version 5.5.3 of the Elo Multi-Touch driver. This issue has not been observed with this driver version.

Keyboard LEDs do not toggle from within the zero client OSD

Some keyboard models have LEDs that will not toggle from within the zero client On-Screen Display (OSD). (30009)

Gemalto Classic TPC does not work in session after the card is removed and reinserted

If a smart card is removed and inserted again when using with Gemalto middleware software and Windows 7, a web browser may not be able to read certificates from the card. (28958)

Disconnecting one display resets Preferred Resolution Override on all displays

When multiple displays have Preferred Resolution Override applied to them, disconnecting one display will clear the override for all displays. (28122)

Cursor movement is erratic with more than one HID interface

Cursor movement on a device that has more than one HID interface demonstrates erratic behavior in the On-Screen Display (OSD). (26361)

Panini Vision X Check Scanner fails to operate

Previously, Panini Vision X Check Scanner failed to operate due to URB transfer size. (25499)

Gemalto IDCore 3020 smart cards is missing correct driver in Windows 7

By default, Gemalto IDCore 3020 smart cards work in pre-session. However, the card does not work while in-session for Windows 7 virtual desktops. (22315) Workaround: Install the correct driver from a default Windows 7 installation:

  1. From the zero client administrative web interface, bridge the smart card reader.
  2. Without the smart card inserted, log in to the virtual desktop with username/password.
  3. Insert the smart card. Windows 7 should recognize the smart card and reader and automatically install the correct drivers.
  4. Log off Windows to disconnect the session.
  5. From the zero client administrative web interface, remove the bridge configuration for the smart card reader.
  6. Log in with the smart card. The smart card should be fully accessible.

OneSign cannot authenticate after changing Session Connection Type

After changing a zero client’s Session Connection Type from View Connection Server + Kiosk to View Connection Server + OneSign, the Zero Client is unable to negotiate a PCoIP session with VMware View using OneSign authentication. (21653) Workaround: Restart the zero client.

After display is turned off, screen does not wake up by pushing zero client button

When the On-Screen Display (OSD) Screensaver timeout expires, it will turn off the display after the end of a PCoIP session brokered by a PCoIP Connection Manager. Clicking the zero client’s physical button does not wake the display. (21484)

OSD cursor briefly stops responding to mouse input

The On-Screen Display (OSD) cursor stops responding to mouse input for a few seconds after pressing the Apply button on the AWI USB Permissions page, or while loading the AWI Attached Devices page. It will behave as expected shortly after. (21382)

Users are prompted with reset message after submitting changes to session configuration options

On the AWI, users will be prompted to reset the zero client after submitting changes to the session configuration advanced options while it is configured for the Direct to Host + SLP Host Discovery type. The reset is not necessary if the only changes is made to the advanced options and if the session type is unchanged. (21157) Workaround: Click the Continue button to skip the reset.

Switching between DVI and DisplayPort connectors may cause screen to go blank on HP Z27i displays

HP Z27i displays connected to a zero client’s DisplayPort connectors may not show the remote desktop content when the zero client starts a PCoIP session to a workstation access card, and the card’s previous session was from a zero client with displays attached to its DVI ports. (19353)
