Rollup 1 released for Citrix XenDesktop 5.6 FP1
Citrix have released a Rollup 1 for Citrix XenDesktop 5.6 FP1 which solves lots of bugs and includes new enhancements.
If you apply this rollup then your VDA becomes to Citrix XenDesktop Version 5.6.200
If you are using HDX 3D Pro then i highly recommend you apply this rollup or you update to this VDA version cause it has the latest codec.
If you are running Citrix XenDesktop 5.1 you first have to apply Feature Pack 1 VDA and then this VDA.

Fixes and enhancements in Rollup for Citrix XenDesktop 5.6 FP1
HDX 3D Pro
- When maximized, applications published on an HDX 3D Pro enabled Virtual Desktop Agent cover the taskbar.
- This fix addresses an issue that can cause the audio service (CtxAudioService.exe) to exit unexpectedly in HDX 3D Pro sessions.
The PICA Display Manager (PicaDispMgr.exe) running in HDX 3D Pro enabled sessions on Windows 7 Virtual Desktop Agents can spike the CPU to over 30% even when the session window is minimized or otherwise idle.
HDX MediaStream
- With HDX Mediastream for Flash enabled, Web sites with Flash content can experience delays of up to 10 seconds to load.
- Important: Before applying this fix on a client device, see Knowledge Center article CTX126817 for important information about how the Dynamic Blacklist feature might affect client-side Flash redirection.With Adobe Flash Player ActiveX 11.3 installed on the endpoint device, Flash content cannot be redirected to be rendered on the client; instead, the content is rendered on the server.To enable this fix in its entirety, you must install both a client hotfix that contains Fix #LA2283 and:
- For XenApp: an HDX Flash hotfix that contains Fix #LA2283
- For XenDesktop: a Virtual Desktop Agent hotfix that contains Fix #LA2283
- Important: Before applying this fix on a client device, see Knowledge Center article CTX126817 for important information about how the Dynamic Blacklist feature might affect client-side Flash redirection.With Adobe Flash Player ActiveX 11.4 installed on the endpoint device, Flash content cannot be redirected to be rendered on the client; instead, the content is rendered on the server.To enable this fix in its entirety, you must install both a client hotfix that contains Fix #LA2565 and:
- For XenApp: an HDX Flash hotfix that contains Fix #LA2565
- For XenDesktop: a Virtual Desktop Agent hotfix that contains Fix #LA2565
HDX MediaStream Windows Media Redirection
- Third party multimedia applications using the HDX MediaStream Multimedia Acceleration feature might exit intermittently.
- When connecting to a Virtual Desktop Agent, multimedia redirected audio can fail for certain thin clients. This issue occurs with those thin clients that lack a head-end mixer for the audio subsystem. The problem arises from the Virtual Desktop Agentâs behavior of forcing the audio playback device open upon connection and not automatically closing it. This, in turn, can prohibit access to the audio device by multimedia redirection.This fix corrects the issue for Virtual Desktop Agents running on non-Windows XP operating systems by suppressing automatic opening of the playback device. To correct the issue for Virtual Desktop Agents running on Windows XP, you must set the following registry key:
- On 32-bit Windows:
HKEY_LOCAL_MACHINE\SOFTWARE\Citrix\GroupPolicy\Default\AudioSettings
Name: EnableForcedDeviceOpenOnXPHost
Type: REG_DWORD
Data: <0 (suppress automatic opening of playback device ); 1 (enable automatic opening of playback device)>
- On 64-bit Windows:
HKEY_LOCAL_MACHINE\SOFTWARE\Wow6432node\Citrix\GroupPolicy\Default\AudioSettings
Name: EnableForcedDeviceOpenOnXPHost
Type: REG_DWORD
Data: <0 (suppress automatic opening of playback device ); 1 (enable automatic opening of playback device)>
- On 32-bit Windows:
- This fix addresses an issue than can cause the video portion of a multimedia file to trail the audio portion slightly when rendering.With Windows Media Redirection enabled, videos fail to play after the following sequence of user actions: Play > Pause > Seek > Play.
HDX Plug and Play
- When reconnecting to a virtual desktop session, any USB optical drives attached to the endpoint are mapped into the reconnected session. This happens if optical drives are permitted in the file redirection policies but USB redirection is disabled.
Installing, Uninstalling, Upgrading
- Uninstalling a Version 5.x Virtual Desktop Agent from a 32-bit Windows XP system fails to remove the picaTWComms.sys file from C:\windows\system32\drivers.
- When using the Receiver for LINUX and “KeyboardLayout=(Server Default)” is configured in the server side default.ica file, the session might default to an incorrect input method (other than the default IME). For additional information, see Knowledge Center article CTX135737.
- This enhancement to Remote PC ensures that the smart card credentials tile rather than the LDAP credentials tile is selected by default when logging on a to a remote PC using a smart card for authentication. After the installation his enhancement is enabled by default. To disable it, you must set the following registry key:HKEY_LOCAL_MACHINE\SOFTWARE\Citrix\PortICA\DefaultCredentialProvider
Name: DisableDefaultCredentialOverride
Type: REG_DWORD
Data: 1 - If Internet Explorer running on a Windows 7 Virtual Desktop Agent prompts for a username and password to access a Web site and incorrect credentials are entered, the subsequent Internet Explorer logon screen is missing the “Use other account” logon option until you exit and restart the browser.
- Changes to session printer properties might be saved and restored even if the printer properties retention policy “Do not retain printer properties” is enabled.
- The Citrix Print Manager Service process might exit unexpectedly.
- Setting the policies, CPU Usage Monitoring, ICA Latency Monitoring, and UPM Logon Time monitoring to âDisableâ does not take effect.
- After upgrading from Version 4 of the Virtual Desktop Agent to a newer version, the Citrix-Multimedia-Flash log is no longer visible in the Event Viewer. This issue occurs on agents running on Windows 7 and Windows Vista.
- Attempts to retrieve policies on a Virtual Desktop Agent from Desktop Director fail. To resolve this issue in its entirety, you must install this fix and then grant “Read” permissions on the agent’s C:\Users\<Username>\Citrix\ folder, including subfolders and files, to the Desktop Director user.
- Attempts to log on to a Virtual Desktop Agent across domains using the NetBIOS name fail. However, users can log on using their fully qualified domain name (FQDN).
- When reconnecting to a disconnected session, previously visible mapped network drives are no longer visible in Windows Explorer.
- Sessions can disconnect unexpectedly, and the disconnect is incorrectly reported as an SSL error on the client, server, or the Secure Gateway.To correct these issues, you must install hotfixes that contain Fix #LA2017 for both XenApp and for XenDesktop.
- The CPU Usage Monitoring fails to honor values other than the defaults.
- The Dependencies tab of the Citrix Desktop Service Properties (Local Computer) window lists four system component dependencies, including a Server component dependency. The Server component dependency is present in error. This fix removes the inaccurate Serverlisting.
- Microsoft Internet Explorer might exit unexpectedly, referencing pseudoserverinproc2.dll, with certain types of Flash content on Web pages.
- Attempts by an endpoint device to reconnect to a disconnected Virtual Desktop Agent might fail indefinitely until the Virtual Desktop Agent is restarted.
- Attempts to reconnect to a Virtual Desktop Agent running on Windows XP might fail with a black screen until the agent is restarted. Also, the session window might revert to the size of the previous connection rather than being full-screen.
- Microsoft Internet Explorer might exit unexpectedly, referencing pseudoserverinproc2.dll, with certain types of Flash content on Web pages.
- Attempts to connect to Version 4 of the Virtual Desktop Agent running on Windows XP might fail during the logon process, displaying only the desktop screen.
- This fix addresses the following issues users can experience when HDX Windows Media redirection is disabled by way of the associated policy (HDX Policy > Machines > Windows Media Redirection):
- Seek is not working properly
- Video becomes unresponsive after Play > Pause > Play operations
- The Group Policy engine (CitrixCseEngine.exe) process can cause the CPU to spike unexpectedly and prevent logons to virtual desktops. To enable this fix, you must install both a Group Policy Client side Extension and a Virtual Desktop Agent hotfix that contains Fix #LA2544.
- Following a ticket validation failure, a pooled Virtual Desktop Agent running on Windows 7 might become inaccessible until the agent is restarted.
- When using smart card authentication, sites in the Intranet zone do not prompt for credentials and fail to load if protected mode is enabled for the Intranet zone. To enable this capability, you must set the following registry key:HKEY_LOCAL_MACHINE\SOFTWARE\Citrix\SmartCard
Name: SupLowIntegrityProc
Type: REG_DWORD
Data: 1
- Virtual Desktop Agents might experience a fatal exception (DRIVER_IRQL_NOT_LESS_OR_EQUAL), on TCPIP.SYS with bugcheck code D1.
- In an RDP session running on a computer or VM with a Virtual Desktop Agent installed, the picaDisplayMgr.exe process can continually start and exit, eventually spiking the CPU. An instance of the same process running in the local console session does not exhibit the issue.
- Attempts to reconnect from a different endpoint can cause the Citrix Audio Service (CTXAudioService.exe) to exit unexpectedly. Repeat attempts can cause the agent to experience a fatal exception, displaying a blue screen.
- After reconnecting to a Windows 7 full-screen Virtual Desktop Agent from a multiple-monitor endpoint, the original positioning of windows across monitors is not retained. Instead, all windows previously positioned on the secondary monitor are positioned on the primary monitor. The issue is related to the Citrix WDDM driver, which installs by default on Windows 7 as part of the Virtual Desktop Agent installation.
- A lock contention can cause the WorkstationAgent.exe process to consume up to 60% of the CPU and up to 500MB of RAM
- After making an RDP connection to a Virtual Desktop Agent, client connection attempts no longer succeed.
