Started a few days ago at most: Agent on Session host no longer communicates properly with WVD

One other power user tip: I found a Powershell cmdlet that makes it really easy to monitor the status of the session hosts so you can see the scheduled task in action.

You can get the cmdlet here:
http://wragg.io/watch-for-changes-with-powershell/

You can run it to monitor session hosts this way:

{ Get-RdsSessionHost -TenantName "TENANT" -HostPoolName "HOST POOL" } | Watch-Command -Verbose -Continuous

If any values like status, heartbeat time, session count, etc change, it prints the output.

iconicmlee Sure!

I believe you will need to configure the task to run with highest privs under an admin account, since it needs to be able to stop and start system services:

<?xml version="1.0" encoding="UTF-16"?>
<Task version="1.2" xmlns="<a href="http://schemas.microsoft.com/windows/2004/02/mit/task" target="_blank">http://schemas.microsoft.com/windows/2004/02/mit/task</a>">
