I have a service that reads from a database a string that is a powershell script. The code snippet from the c# service is:

   psi = new ProcessStartInfo(psPath, "-executionpolicy bypass -file c:\temp\HeartBeatScript.ps1  -verbose");
   psi.CreateNoWindow = false;
   psi.UseShellExecute = true;
   psi.Verb = "runas";
   psi.WindowStyle = ProcessWindowStyle.Hidden;
   Process.Start(psi);

The script that is being run is as follows:

&{
Start-Transcript c:tempPSTranscript.txt
Set-PSDebug -Trace 2
$time = Get-Date
write-host "Starting" $time
$ServiceName = 'UsageMonitor'
$UpdateFromPath = '\FileShareTest SoftwareUserShare*'
$CopyTo = 'C:temp'
$arrService = Get-Service -Name $ServiceName

Start-Sleep -seconds 60
$time = Get-Date
write-host "Stopping service" $time
while ($arrService.Status -eq ''Running'')
{
    Stop-Service $ServiceName
    Start-Sleep -seconds 35
    $arrService.Refresh()
}
Start-Sleep -seconds 10

$time = Get-Date
write-host "Copying Files" $time
Copy-Item -force -path $UpdateFromPath -destination $CopyTo
Start-Sleep -seconds 30

$time = Get-Date
write-host "Starting Service" $time
Start-Service $ServiceName
Start-Sleep -seconds 35
$arrService.Refresh()
while ($arrService.Status -ne 'Running')
{
    Start-Service $ServiceName
    Start-Sleep -seconds 35
    $arrService.Refresh()
}
$time = Get-Date
write-host "complete" $time
} *>c:tempPSScriptOut.txt

The redirected output of the script (PSScriptOut.txt) is

I’ve left the debugging attempts in the code/scripts.
I see the service stopping. I see the service start.
What I don’t see are the files copied in the middle.

If I run the same script in the PSE environment, everything works. Service stops. Files are copied. Service starts.

I have a mechanism where I could supply alternate credentials for the PS script to run under. But, that would be inconvenient since that would involve another department.

Ideas on how I might get this to work?
