I created the following script to check the website status and the IIS instance status. When I manually runs it from PowerShell ISE with Adminstrator, it works fine but when I triggered from Task Scheduler, it just didn’t worked! And it was due to GET-WEBSITESTATE as this cmdlet required to run from PS ISE Administrator. My question, what is the command need to setup in Task Scheduler? Currently, i setup the task schedule with the following: Program/Script: Powershell.exe Add arguments: powershell -executionpolicy bypass -file "D:\PS\CheckPMRWebpage\Code\Monitor PMR webpage 6-1.ps1

## The URI list to test 
$URLListFile = "D:\PS\CheckPavcapWebpage\Code\PavCapurlList.DAT"  
$URLList = Get-Content $URLListFile -ErrorAction SilentlyContinue 
$Result = @() 

  Foreach($Uri in $URLList) { 
  $time = try{ 
  $request = $null 
   ## Request the URI, and measure how long the response took. 
  $result1 = Measure-Command { $request = Invoke-WebRequest -Uri $uri } 
  $result1.TotalMilliseconds 
  }  
  catch 
  { 
   <# If the request generated an exception (i.e.: 500 server 
   error or 404 not found), we can pull the status code from the 
   Exception.Response property #> 
   $request = $_.Exception.Response 
   $time = -1 
  } 
  #   $lStatusCode = [int] $request.StatusCode
  # if ($lStatusCode -eq 401){
  #  $linfo = "The site is ok."
  # }

  $result += [PSCustomObject] @{ 
  Time = Get-Date; 
  Uri = $uri; 
  StatusCode = [int] $request.StatusCode; 
  StatusDescription = $request.StatusDescription; 
  ResponseLength = $request.RawContentLength; 
  TimeTaken =  $time;   
  } 
}
