Intermittently during a logoff from a XenDesktop session, a blank desktop is presented with a message that the connection was interrupted, and that Citrix Receiver tries to reconnect.

Caution! Using Registry Editor incorrectly can cause serious problems that might require you to reinstall your operating system. Citrix cannot guarantee that problems resulting from the incorrect use of Registry Editor can be solved. Use Registry Editor at your own risk. Be sure to back up the registry before you edit it.

Solution 1: Follow the below steps to identify the driver causing the problem.

1. On the VDA, where the issue is happening, run elevated Command Prompt.
2. Run the command fltmc to see all the filter drivers loaded on the VDA.
3. Check if you have any drivers named TDx.sys. (where 'x' is a wild card, so it could be anything like TDabc.sys, TDxyz.sys or so)
4. Disable that filter driver one by one using "sc config "TDx.sys" Start=disabled" command.
5. Once disabled, you should not see the "Connection Interrupted" anymore.

Solution 2:

Uninstall existing VMWare Tool
Download VMWare Tool version 10.3.5 and install excluding SVGA Driver.
