You have to use `Get-Service` to get the remote service: $service = Get-Service -Name DeathStar -ComputerName Yavin $service.Stop() $service.Start() # or (and no, you can't pipe the service directly to `Restart-Service`) Get-Service -Name DeathStar -ComputerName Yavin | ForEach-Object { Restart-Service -InputObject $_ } This function does all this unnecessary work for you. You'll get an error if you attempt to restart a non-existent service. .EXAMPLE Restart-CRemoteService -Name DeathStar -ComputerName Yavin Restarts the `DeathStar` service on Yavin. If the DeathStar service doesn't exist, you'll get an error. #> [CmdletBinding(SupportsShouldProcess=$true)] param( [Parameter(Mandatory=$true)] [string] # The service name to restart. $Name, [Parameter(Mandatory=$true)] [string] # The name of the computer where the service lives. $ComputerName ) Set-StrictMode -Version 'Latest' Use-CallerPreference -Cmdlet $PSCmdlet -Session $ExecutionContext.SessionState $service = Get-Service -Name $name -ComputerName $computerName if($service) { if($pscmdlet.ShouldProcess( "$name on $computerName", "restart")) { $service.Stop() $service.Start() } } else { Write-Error "Unable to restart remote service because I could not get a reference to service $name on machine: $computerName" } } |
