VM's Power State Does Not Update And Shows As “Unknown” After vCenter Server Reboots

This is an issue with Citrix hypervisor communication library plugin since version Xenapp/XenDesktop version 7.16.

When vCenter server goes alive after reboot i.e “https://<vCenter FQDN>/sdk” becomes accessible, BrokerHostingPlugin still fails to login the vCenter server with exception “The session is not authenticated.”.

Client Drive Mapping Fails when File Size is Larger than 4GB

In XenApp and XenDesktop, very large files that have a file size greater than 4GB are not supported with Client Drive Mapping.

For Example, when viewing a file which is greater than 4GB using a published Windows Explorer instance in a XenApp Client Mapped Drive, file size will be incorrectly displayed.

The following error message might appear:

“The file <filename> is too large for the destination file system”

When copying a file with file size greater than 4GB using a CDM mapped drive, the file is partially copied, resulting in an incomplete target file being written.

Citrix UPS Printers are not visible via Control Panel, Devices And Printers


This is an known issue with printers provided by Citrix Universal Printer server on windows operating systems Windows Server 2019, Windows Server 2016, Windows 10, Windows Server 2012r2, Windows Server 2012.

Citrix is working with Microsoft to correct this interaction between Microsoft operating systems and Citrix universal print server print provider.


Citrix Documentation:

This issue has been documented in our XenApp/XenDesktop documentation since 7.5

  • Universal Print Server printers selected in the virtual desktop do not appear in the Devices and Printers window in Windows Control Panel. However, when users are working in applications, they can print using those printers. This issue occurs only on Windows Server 2012, Windows 2012 R2 , Windows 10 and Windows 8 platforms. [#335153]

Microsoft Documentation:

The Device Setup Manager service is discussed in the following article from Microsoft it applies to both Windows 8 and Windows 2012.

Device setup user experience in Windows 8

Microsoft released a hotfix for server 2012r2 which partially addressed some issues with 3rd party print provider visibility in newer windows releases.

However this was not a complete solution, and printers provided by Citrix Universal Print Server remained not visible.​

HDX Flash Redirection Compatibility

HDX Flash Redirection is a technology that allows Flash-based videos to be rendered on the end user device (Windows or Linux) while appearing seamlessly integrated with the server-side web browser. HDX Flash provides a better user experience by offloading Adobe Flash rendering from the Citrix XenApp or XenDesktop server to the user device. The objective is to offload 80% or more of websites that leverage Flash. When Adobe Flash content cannot be redirected to the user device, the technology attempts to gracefully fall back to server-side rendering. Websites that cannot use Flash Redirection are blacklisted, either automatically by the software or manually by a system administrator.

If client-side Flash rendering is not desired, the HDX Flash Redirection technology can be disabled by using policies but the scalability benefits of HDX Flash Redirection are lost.

Compatibility Matrix

HDX Flash Redirection behavior might be affected by the Adobe Flash version, the XenApp or XenDesktop VDA version, as well as the Receiver version used to access applications and desktops. The browser version seems to have the largest impact on the specific Flash Redirection behavior that could be experienced in your environment.

Citrix has tested a variety of Adobe Flash and Internet Explorer versions against different XenApp and XenDesktop versions to determine the stability of Flash Redirection with these different combinations and to ensure that Flash Redirection works as expected. The following matrix comprises the scope of our testing:

Note

  • On July 25, 2017, Adobe announced End of Life (EOL) for Flash. Adobe plans to stop updating and distributing the Flash Player at the end of 2020. Microsoft announced that they are phasing out Flash support in Internet Explorer before the Adobe date. They are removing Flash from Windows by the end of 2020. When that happens, users can no longer enable or run Flash in Internet Explorer. Citrix aligns with Microsoft policy and continues to maintain and support HDX Flash Redirection until the end of 2020. More information available on https://docs.citrix.com/en-us/xenapp-and-xendesktop/7-15-ltsr/multimedia/flash-redirection.html
  • Adobe no longer has Extended Support Release (ESR) versions of Flash. Customers are recommended to use the supported versions of Flash as outlined in the matrix below.
  • Some websites stream content using HTML5 by default, such as Youtube.com and may prompt to install Flash even after adding to Compatibility View. To use Flash Redirection on such websites, Emulation Mode should be used.(for example IE9 mode) The later section of the article outlines steps to enable Emulation Mode.
  • Beginning January 12, 2016, Microsoft supports only the most current version of Internet Explorer available for an operating system. Flash Redirection will be supported on the latest version of Internet Explorer supported on the operating system. For details, refer to Microsoft Lifecycle Support policy for Internet Explorer.
Platforms
Versions Tested Up To
Adobe Flash 32.0 32.0.0.207
Internet Explorer
11
11.0.10240.17319
Receiver for Windows 4.9 4.9.6000
Workspace App 1905

Citrix recommends the XenApp or XenDesktop component updates below used in our testing to achieve the best Flash Redirection experience.

These hotfixes contain several Flash Redirection related fixes that provide more stability to environments using Flash Redirection, particularly those which resulted in blacklisting websites and Flash videos not playing.

Website Content: Adobe Flash technology and content is frequently updated on many websites that might impact Flash Redirection particularly with Internet Explorer 11. Some of these website specific issues can be resolved by one of the following workarounds:

  • Enable Internet Explorer Compatibility View and add the website(s) to the list.
  • Enable Emulation Mode on the user device. In Internet Explorer, on the Tools menu, click F12 Developer Tools. In the far left of the DOM Explorer screen, scroll down the list and select the Emulation icon. In Document Mode, select 9 or 10. Microsoft Enterprise Mode Site List Manager can be utilized to automate the Document Mode.
