Horizon 711. Win 10 1809
I have a linked clone pool, that when I view the sessions, there are up to four sessions that are Console, not going through the gateway, the user is Administrator. The sessions were all opened with a minute of each other, and the ones I found today have been connected for 25 days. Disconnecting is not available as an option so I have the reset the VM.
I believe these connections are related to logging into the Master image in vSphere with Remote Console. How that spawns connection to VM's in the pool I have no idea, but apparently that is what is happening. I never log into the VM's fro the pool with RC. I am also the only one who works on Horizon.
