I have found that the session hosts often end up reporting a status of ‘Needs Assistance’. This can be caused by updates having been applied that require a reboot to complete…and other unknown issues. Often a reboot will sort them out. So I developed a simple script to assist.
The following script will allow you to specifiy the only the VM’s in a Host Pool and only those that ‘Need Assistance’ and that have no active sessions on too….or not!
Save the full script to a file called RebootHosts.ps1
#———————————————————[Script Parameters]——————————————————
[CmdletBinding()]
Param (
#Script parameters go here
[Parameter(mandatory = $true)]
[string]$HostPoolName,
[Parameter(mandatory = $true)]

[Parameter(mandatory = $false)]
[switch]$OnlyDoIfNeedsAssistance
)

$rebooted = 0
$skippedSessions = 0

$sessionHosts = Get-AzWvdSessionHost -ResourceGroupName $HostPoolResourceGroupName -HostPoolName $HostPoolName
foreach ($sh in $sessionHosts)

$VMName = $sh.Name.Split(“thattruyen/”)[1]
$VMName = $VMName.Split(“.”)[0]
$Session = $sh.Session
$Status = $sh.Status
$UpdateState = $sh.UpdateState
$UpdateErrorMessage = $sh.UpdateErrorMessage

Write-output “!! The VM ‘$VMName’ is not in ‘Needs Assistance’ state, so will NOT be rebooted. !!”
elseif ($SkipIfActiveSessions -and $Session -gt 0)

You will need to log in to Azure and select your subscription in the normal way using:
Login-AzAccount
Select-AzSubscription “my-subscription”
You can then simply run the script as follows:
.RebootHosts.ps1 -HostPoolName “my-host-pool” -HostPoolResourceGroupName “my-host-pool-rg” -OnlyDoIfNeedsAssistance -SkipIfActiveSessions
The following section outlines how to reset a saved desktop in the PCoIP Client. You can reset to a virtual desktop by following the steps outlined below:
You can select a Fusion command to reset a virtual machine, much as you would press the reset button on a physical computer when it becomes unresponsive.
Caution: Resetting the virtual machine can cause data loss.
If the remote desktop operating system stops responding, you might need to restart a remote desktop. Restarting a remote desktop is similar to using the Windows operating system restart command. The remote desktop operating system usually prompts you to save any unsaved data before it restarts.
You can restart a remote desktop only if a Horizon administrator has enabled the restart feature for the remote desktop and the remote desktop is powered on. You can restart only one remote desktop at a time.
For information about enabling the desktop restart feature, see the Setting Up Virtual Desktops in Horizon or Setting Up Published Desktops and Applications in Horizon document.
Horizon Client prompts you to confirm the restart action.
The operating system in the remote desktop restarts and the client disconnects and logs off from the remote desktop.
Wait an appropriate amount of time for the system to restart before you attempt to reconnect to the remote desktop.
If restarting the remote desktop does not solve the problem, you might need to reset the remote desktop. See Reset Remote Desktops or Published Applications.
