Powershell to restart a service

Recently I had a service on a server that keeps stopping, and I needed to check to make sure it's started, and if not then I need to restart it. To fix this I wrote a powershell script to do this, and then put it on a scheduled task to run it regularly.

I created a PowerShell script like this one, and saved it to the hard drive as RestartService.ps1

$ServiceName = 'Serenade'
$arrService = Get-Service -Name $ServiceName

while ($arrService.Status -ne 'Running')
{

    Start-Service $ServiceName
    write-host $arrService.status
    write-host 'Service starting'
    Start-Sleep -seconds 60
    $arrService.Refresh()
    if ($arrService.Status -eq 'Running')
    {
        Write-Host 'Service is now Running'
    }

}

Then I opened Task Scheduler, and I created a task that runs this script. The actions for the script are like this:

• Actions: Start a program
• Program/Script: PowerShell.exe
• Add arguments: -ExecutionPolicy Bypass -File RestartService.ps1 -skipadmincheck
• Start in: D:\PowerShell

The "Start in" location is where you saved the PowerShell script.

Now you have a scheduled task that will check this service on the schedule that you define.
