Powershell Restart Service

I'm trying to do this command from a remote server, but I keep getting any error. I tried adding the remote machine as a trusted host, but that still doesn't work.

$session = New-PSsession -Computername "123.123.123.123"
Invoke-Command -Session $Session -ScriptBlock {Restart-Service "SERVICENAMEHERE"}
Remove-PSSession $Session

failed with the following error message : The WinRM client cannot
process the request. Default authentication may be used with an IP address under the following conditions: the transport is HTTPS or the
destination is in the TrustedHosts list, and explicit credentials are provided. Use winrm.cmd to configure TrustedHosts. Note that computers in
the TrustedHosts list might not be authenticated. For more information on how to set TrustedHosts run the following command: winrm help config.
For more information, see the about_Remote_Troubleshooting Help topic.

Have you tried putting authentication details into the command?

No real need for a remote session here; Restart-Service doesn't have its own -ComputerName argument, but it accepts a service object retrieved from a remote machine with Get-Service:

Restart-Service -InputObject (Get-Service -Name "SERVICENAMEHERE" -ComputerName "123.123.123.123")

oBdA, where can I put auth details?

Also how can I make that so someone can just double click on it and it runs. Right now if I save it as a ps1, it just opens in notepad

Save this as Whatever.cmd. It's PowerShell at heart, but wrapped in batch.

@PowerShell.exe -Command "Invoke-Expression -Command ((Get-Content -Path '%~f0' | Select-Object -Skip 3) -join [environment]::NewLine)"

@exit /b
$ServiceName = 'Spooler'
$UserName = 'SomeUser'
$ComputerName = 'SomeComputer'
$Credential = Get-Credential -Message "Credentials to restart '$($ServiceName)' on '$($ComputerName)'" -UserName $UserName
$TimeOut = 120	## seconds

$gwmiArgs = @{

	'ComputerName' = $ComputerName
	'Filter' = "Name='$($ServiceName)'"
	'Class' = 'Win32_Service'
}
$Service = Get-WmiObject @gwmiArgs -ErrorAction Stop
If (-not $Service) {
	Throw "Service '$($ServiceName)' not found on '$($ComputerName)'!"
}

$StopDate = (Get-Date).AddSeconds($TimeOut)
"Stopping '$($ServiceName)' on '$($ComputerName)' ." | Write-Host -ForegroundColor White -NoNewline
$Result = $Service.StopService()

Do {

oBdA, this would work perfect, but I need a way to store the password also. Any ideas?

oBdA

What's the exact purpose of this script, that is, who will it run where and why?

Pumpernickel

ASKER

It will be pushed via Citrix to a client who needs to restart a service every once in a while for their application

Any ideas?

oBdA

How savvy is this client? The problem with this is that the password can be revealed with little effort.
What is "once in a while", and why?

Pumpernickel

ASKER

I'm not worried about the password being revealed as the service has special permissions allowing it to be controlled by only that account. That special account can't do anything else.
