No Active Session from User but Stayed as Disconnected. - Pooled Collection

Hi,

1. I have a user tim.holland that remotes into a Pooled VM. I believe he turned off his physical computer with this Remote Session active so now the status is "Disconnected" and VM is OFF. I couldn't start the Pooled VM so I restored to its checkpoint but Disconnected status remains. Tim cannot log back into one of these pooled VMs.

2. I tried to LOG OFF user from the Connections windows in Server Manager-->Remote Desktop Services-->Collection but error.

3. I do not have Cluster. Usually, migrate the VM to another Node will work but unfortunately this is only 1 server.

Any help is appreciated.

Thank you

Tuan
