Trigger Script on VPN Connection

If you want to add additional triggers replace the logon only trigger from this line with the following content:

$trigger = New-ScheduledTaskTrigger -AtLogOn

$class = cimclass MSFT_TaskEventTrigger root/Microsoft/Windows/TaskScheduler
$trigger2 = $class | New-CimInstance -ClientOnly
$trigger2.Enabled = $True
$trigger2.Subscription = '<QueryList><Query Id="0" Path="Microsoft-Windows-NetworkProfile/Operational"><Select Path="Microsoft-Windows-NetworkProfile/Operational">*[System[Provider[@Name=''Microsoft-Windows-NetworkProfile''] and EventID=10002]]</Select></Query></QueryList>'

$trigger3 = $class | New-CimInstance -ClientOnly
$trigger3.Enabled = $True
$trigger3.Subscription = '<QueryList><Query Id="0" Path="Microsoft-Windows-NetworkProfile/Operational"><Select Path="Microsoft-Windows-NetworkProfile/Operational">*[System[Provider[@Name=''Microsoft-Windows-NetworkProfile''] and EventID=4004]]</Select></Query></QueryList>'

And adjust the registration of the scheduled task with the newly definded triggers:

$null=Register-ScheduledTask -TaskName $schtaskName -Trigger $trigger,$trigger2,$trigger3 -Action $action  -Principal $principal -Settings $settings -Description $schtaskDescription -Force
