I've been actively testing WVD since it's preview release and this past weekend the host machines began reporting more active sessions than there actually were.
Get-RdsUserSession reports a single active connection:
Get-RdsSessionHost reports 3 active sessions:
As a result new connection requests are being rejected because the WVD Hosts think they are at max active sessions.
Again, this only started happening this weekend.
Any insight is greatly appreciated.
@iggyemu : Thanks for reaching out on this! This bug was reported recently, and we are actively working on it. If you are able to and restart the virtual machine, the extra sessions should go away.
