Known issues with Server 2019 and XenDesktop 7.15 CU3

Jens Strohschnitter1709152492


Does anyone know if the reported issues under


will be fixed in a Xendesktop 7.15 LTSR release ?



- Windows 2019 published desktop cannot be locked through start menu or Ctrl+Alt+Del. [HDX-15327]

- Grey screen appears when trying to reconnect to a disconnected session on Windows Server 2019 Virtual Apps server.

- When a seamless application is closed, sessions are left in disconnected state on the Virtual Apps server and continue to show as “Active” in Studio with “Application not running” Application State. [HDX-16230]


are "showstoppers" in our environment to switch from Server 2016 "1607" to 2019 "1809".


With 7.15 CU3 the reported issues still appear.

Hi Jens,

are you sure you mean 7.15 LTSR?

Server 2019 is not even supported on 7.15 LTSR. (… and will not be in future)


System-Requirements 7.15 LTSR: https://docs.citrix.com/en-us/xenapp-and-xendesktop/7-15-ltsr/system-requirements.html - No Support for Server 2019

System-Requirements 1811: https://docs.citrix.com/en-us/citrix-virtual-apps-desktops/system-requirements.html - Support for Server 2019

Having these issues aswell.


Tried upgrading the Windows Server 2019 VDA from 7.15 to 1811 and it was successfully installed.

Unfortunately it just remains as unregistered on the DDC.

Tried the usual troubleshooting, logs werent helpful.


Had to roll back.   is a 1811 agent not compatible with 7.15 farm ??
