MicrosoftHow to troubleshoot Unavailable Status of SessionHost
Martinsd Thanks for opening the support ticket. That is the right approach as we would need to troubleshoot where the failures are coming from by looking at your logs.
Hi,
i can relate to this. Created multible tenats via powershell. (Azure template does not work ?).
Each VM regsitered in the host pool successfully. But each VM is unavailable. Tried different VM´s and different Host Pools.
- Eventlog displays an error like this:
"Microsoft.RDInfra.Monitoring.AgentMonitoringService.AgentMonitoringServiceWorker
Fail to set default dimensions Invalid Operation: Fail to set default dimensions, error code is 2147942487.. Error code is 80070057"
- I think the SxS Network Stack is broken , because i´m not able to update it (corrupt ressources?).
- qwinsta is not very helpfull.
SESSIONNAME USERNAME ID STATE TYPE
services 0 Disc

corrupt installation files? Anyone with a brilliant idea?

Fix: Follow these instructions to manually update the agent.
Download a new version of the agent on the session host VM.
Launch Task Manager and, in the Service Tab, stop the RDAgentBootLoader service.
Run the installer for the new version of the Windows Virtual Desktop Agent.
When prompted for the registration token, remove the entry INVALID_TOKEN and press next (a new token isn't required).
Complete the installation Wizard.
Open Task Manager and start the RDAgentBootLoader service.
