PS: Scheduled task

Hi,

I have a PS script which sets a PS scheduled task BUT it lacks some things = setting username to run with + 'run whether user is logged on or not', configure task for Windows 2012 R2 instead of default ".

Can't figure out howto do this in Powershell.

Please advise.

This is the script:

function new-PSScheduledTask
{

param(

[Parameter(Mandatory = $true)][string[] $Computername,
[Parameter(Mandatory = $true)][string] $ScriptPath,
[Parameter(Mandatory = $true)][string]$FunctiontoExecute,
[Parameter(Mandatory = $true)][string]$Taskname,
[Parameter(Mandatory = $false)]$TriggerTime = '6:00'
)

invoke-command -ScriptBlock {

$TriggerFrequency = @{ Daily = $true }
$Trigger = New-ScheduledTaskTrigger -At $using:TriggerTime @TriggerFrequency

$commandtoexecute = "& {. $using:ScriptPath;$using:functiontoexecute}"
$argument = "-NoProfile -WindowStyle Hidden -command $commandtoexecute"

$action = New-ScheduledTaskAction -Execute 'Powershell.exe' -Argument $argument
Register-ScheduledTask -Action $action -Trigger $trigger -TaskName $using:TaskName -Description $using:TaskName -RunLevel Highest #-User $UsernameTorunScheduledJob
} -ComputerName $Computername

Write-Output "TO SET: username to run with + 'run whether user is logged on or not', configure for Windows 2012 R2 "
}

To run the task as a specific user, use New-ScheduledTaskPrincipal.

I believe that if you save the password, the task will run whether the user is logged in or not.

Does not work
Cannot validate argument on parameter 'UserId'. The argument is null or empty. Provide an argument that is not null or empty, and then try the command again.

Command is
new-PSScheduledTask -Computername servername -ScriptPath 'e:\myscript.pst' -FunctiontoExecute 'Get-something' -Taskname 'sometask'

then it prompts for user and password but it throws an error.

Well this example works:

$action = New-ScheduledTaskAction -Execute 'Powershell.exe' -Argument '-NoProfile -WindowStyle Hidden -command "& {get-eventlog -logname Application -After ((get-date).AddDays(-1)) | Export-Csv -Path c:\Reports\applog.csv -Force -NoTypeInformation}"'
$trigger =  New-ScheduledTaskTrigger -Daily -At 11am
Register-ScheduledTask -Action $action -Trigger $trigger -TaskName "AppLog" -Description "Daily dump of Applog"

So It should be related to the task itself, so the error should be within the Scriptblock:

#$action = New-ScheduledTaskAction -Execute foo.exe -Argument "bar baz"
    $principal = New-ScheduledTaskPrincipal -UserId $UserName -LogonType ServiceAccount -RunLevel Highest
    $settings = New-ScheduledTaskSettingsSet -MultipleInstances Parallel 

    $TriggerFrequency = @{ Daily = $true }
    $Trigger = New-ScheduledTaskTrigger -At $using:TriggerTime @TriggerFrequency 
  
    $commandtoexecute = "& {. $using:ScriptPath;$using:functiontoexecute}"
    $argument = "-NoProfile -WindowStyle Hidden -command $commandtoexecute"
      
    $action = New-ScheduledTaskAction -Execute 'Powershell.exe' -Argument $argument
    Register-ScheduledTask -Action $action -Trigger $trigger -TaskName $using:TaskName -Description $using:TaskName  -RunLevel Highest -Principal $UserName -Settings $settings -Password $pwd

Will check it later.
