Scheduled Task - Powershell Script Error

Hi,

I have a powershell script for emailing a user when their AD password is due to expire. I works fine when run from the PowerGUI script editor but when I run it as an ActiveRoles scheduled task it fails.

It immediately fails by throwing "Domain 'MaximumPasswordAge' password policy is not configured."

I removed all the script logic and hard coded the $MaxPassAge to 45 then it fails to run Get-QADUser.

Its almost as if the ActiveRoles powershell modules are missing from the server but they are there and other policy scripts run fine using ActiveRoles modules.

Anyone got any ideas?

$ReqVersion = [version]"1.2.2.1254"
$QadVersion = (Get-PSSnapin Quest.ActiveRoles.ADManagement).Version

if($QadVersion -lt $ReqVersion)
{
    throw "Quest AD cmdlets version '$ReqVersion' is required. Please download the latest version"
}

function Send-Mail
{
   param($SmtpServer,$From,$To,$Subject,$Body)
   $smtp = new-object system.net.mail.smtpClient($SmtpServer)
   $mail = new-object System.Net.Mail.MailMessage
   $mail.from= $From
   $mail.to.add($To)
   $mail.subject= $Subject
   $mail.body= $Body
   $smtp.send($mail)  
}

$MaxPassAge = (Get-QADObject (Get-QADRootDSE).defaultNamingContextDN).MaximumPasswordAge.days

if($MaxPassAge -le 0)
{ 
   throw "Domain 'MaximumPasswordAge' password policy is not configured."
}

$DaysToExpire = 60 
$MailFrom = "helpdesk@domain.co.uk"
$PSEmailServer = "cas01"

Select-Object Name,Email,@{Name="Expires";Expression={ $MaxPassAge - $_.PasswordAge.days }} |`
Where-Object {$_.Expires -gt 0 -AND $_.Expires -le $DaysToExpire } | Foreach-Object {
 
$Subject="Password reminder: Your password will expire in $($_.Expires) days"
 
if($PSVersionTable)
  {

     Send-MailMessage -From $MailFrom -To $_.Email -Subject  $Subject -Body  $Subject
