Hi, same problem today again. 2 out of 5 Session Hosts went unvailable. I have already created a MS Ticket a month ago, on the first time of the issue. Microsoft said this is not a global problem. This should be the solution they said:

- Remove the session host from the host pool
- Generate a new registration key for the VM
- Reinstall the agent and boot loader
- Restart Session Hosts

I have done all this steps one month ago. But now same problem...

Anyone got a other idea?

mariolener , I am also seeing this event in my logs. I had to restart our VDI instance for a user who was seeing issues, but at the expense of the others who weren't (it's a shared instance). We're using Sophos endpoint instead of Defender, though I'm sure some of the process is still present, even if AV duty has been handed off.

We have not seen this issue arise again yet (AVD in Aus East, Meta data in East US)

note: our SH agent versions is now listed as: 1.0.5739.9800, as normal there in nothing in the whats new KB about it so no idea if this has any fixes/includes new issue https://learn.microsoft.com/en-us/azure/virtual-desktop/whats-new-agent

Agent appears to have been updated sometime this week.
