远程启动服务

Question

I am trying to start a service remotely after user input.

function Start_Service {
    $ComputerName = $txb_hostname.Text

    [void][Reflection.Assembly]::LoadWithPartialName('Microsoft.VisualBasic')

    $title = 'Start Service'
    $msg   = 'Enter Service Name (e.g. AppVClient):'

    $ServiceName = [Microsoft.VisualBasic.Interaction]::InputBox($msg, $title)

    try {
        (Get-WmiObject Win32_Service -ComputerName $ComputerName -filter "Name='$ServiceName'").StartService()
        LogWrite "$ServiceName started."
    } catch {
        LogWrite "Unable to stop $ServiceName"
    }
}

It just returns

unable to start "service"

almost like the

(Get-WmiObject Win32_Service -Filter -ComputerName $ComputerName "Name='$ServiceName'").StartService()

doesn't work.

Any ideas why it isn't working?

Edit:

Actual error message from the catch block:

Missing an argument for parameter 'Filter'. Specify a parameter of type 'System.String' and try again.

Answer 1

(Get-WmiObject Win32_Service -ComputerName $ComputerName -Filter "Name='$ServiceName'").StartService()
