This script restart the service name “SMS Agent Host” on the servers listed in the file C:\temp\BOOK1.txt
Script :
ForEach($MachineName In $hosts){
$service = Get-Service -ComputerName $MachineName -name "sms agent host"
Write-Host $MachineName, $service.status, $service.name
(new-Object System.ServiceProcess.ServiceController('sms agent host',$MachineName)).Stop()
(new-Object System.ServiceProcess.ServiceController('sms agent host',$MachineName)).WaitForStatus('Stopped',(new-timespan -seconds 15))
(new-Object System.ServiceProcess.ServiceController('sms agent host',$MachineName)).Start()
(new-Object System.ServiceProcess.ServiceController('sms agent host',$MachineName)).WaitForStatus('Running',(new-timespan -seconds 15))
$service = Get-Service -ComputerName $MachineName -name "sms agent host"
Write-Host $MachineName, $service.status, $service.name

ServiceController Class
Represents a Windows service and allows you to connect to a running or stopped service, manipulate it, or get information about it.
Namespace: System.ServiceProcess
Assembly: System.ServiceProcess (in System.ServiceProcess.dll)
The following example demonstrates the use of the ServiceController class to control the SimpleService service example.
