Hello, we are currently face with an issue with a small subset of our VM's These are full clones, Windows 7 desktops. We are connecting via Wyse P25 Zero clients with firmware 4.1.2. From time to time (not always, not consistently) the VM will give a black screen after the user returns from a time away from their desk. When this happens, we see data such as the following in the PCoIP server log.

The behaviour on the user end is that they get a black screen, followed by a disconnect. The view connection manager console reports them as "connected". We are forced to reset their VM or reboot from vSphere in order to get them reconnected. We found a VMware KB here which indicated this was a result of the computer putting the displays to sleep (in the power policy), so we implemented a group policy to set this to "never" (it also says the issue was resolved after View 5.0, while we are running 5.2). Issue still occuring. Recently, Teradici support (we have a case open with them as well as with VMware) suggested we disable the Shoretel Desktop Sharing Accelerator, so we tried this. Issue still occurred today.
So, has anyone in the community ever come across this, and were you able to fix it? Our users are getting extremely frustrated.
