I have come across a weird issue while running a PowerShell script through task scheduler. Below is the simple script which would open all the sites of a SharePoint farm in IE browser.
Add-PsSnapin Microsoft.SharePoint.PowerShell
$ShowIE = $True
$LogFile = "E:\Scripts\Warmedup_Sites.log"
$ie=New-Object -ComObject "InternetExplorer.Application"
$ie.visible = $ShowIE
Get-SPSite -Limit ALL | Get-SPWeb -Limit ALL | ForEach-Object{
$ie.navigate($_.url)
while ($ie.Busy -eq $true){
Start-Sleep -Milliseconds 1000;
}
add-content -path $LogFile -value $("[" + (get-Date).ToString() + "] " + $_.url)
}
$ie.quit()
1. In the 1st case the script runs successfully only when the powershell console is opened as "Run as adminstrator". Otherwise it throws below error. The account am running is already part of server administrators group, is a SharePoint Farm administrator and is a domain account

2. In the 2nd case, when i run the same PowerShell script through a task scheduler, it fails again with below error. The task is set to "Run with highest privileges". And in actions tab am running like "PowerShell.exe -ExecutionPolicy Bypass E:\Scripts\Warmup_AllSites.ps1". I have gone through several blogs and forums related to this error but nothing helped me. I dont think this is a permission issue anywhere. It seems like the COM object is losing the reference and throwing the error when referred. Can someone please help me in this regard.
