PowerShell Script to Stop a service on multiple remote machines - powershell

Question

I am trying to disable a service running on 250+ PCs. I would like to have a PowerShell script I can execute on a random PC in the network and let it disable a service on every PC I specify in an txt file. It's always the same service. The script should also ask for the credential of the PC that it is trying to connect to.
This is a Script to set DNS on every PC in computer.txt. It asks me for the "administrator" password for every PC.
function Set-DNSWINS {
#Get NICS via WMI
$remoteuser = get-credential $_\administrator
$NICs = Get-WmiObject -Class Win32_NetworkAdapterConfiguration -Credential $remoteuser -ComputerName $_ -Filter "IPEnabled=TRUE"
Get-WmiObject -Class Win32_NetworkAdapterConfiguration -Credential $remoteuser -ComputerName $_ -Filter "IPEnabled=TRUE"
foreach($NIC in $NICs) {
$DNSServers = "192.168.3.12","192.168.0.77"
$NIC.SetDNSServerSearchOrder($DNSServers)
$NIC.SetDynamicDNSRegistration("TRUE")
#$NIC.SetWINSServer("12.345.67.890", "12.345.67.891")
}
}
function Get-FileName {
$computer = Read-Host "Dateiname mit Computernamen"
return $computer
}
Get-Content computer.txt | ForEach-Object {Set-DNSWINS}

Answer 1

You can stop a service from the commandline using
net stop "servicename"
or in PowerShell
Stop-Service "serviceName"
There are probably better ways to automate this across multiple machines than your script.

Answer 2

Can use Set-Service to disable a service and Invoke-Command to run it remotely. Note you need to run Enable-PSRemoting on the remote computer and configure WSMAN to allow connecting to the remote PC:
function MyFunction{
$remoteuser = get-credential $_\administrator
$service = "MyService"
Invoke-Command -computer $_ -credential $remoteuser -scriptblock {
Stop-Service $service
Set-Service $service -startuptype Disabled
}
}
function Get-FileName {
$computer = Read-Host "Dateiname mit Computernamen"
return $computer
}
Get-Content computer.txt | ForEach-Object {MyFunction}
