Question

I want to write window service which manages another window service and checks if it is stopped or running.

If it is stopped then my root service starts service again.

My root service is running at a certain times.

Answer 1

Create a windows Service which monitors your service . The code in your service will be

 var Service = new ServiceController(servicetowach);
                    if (Service.Status != ServiceControllerStatus.Running
                        && Service.Status != ServiceControllerStatus.StartPending)
                    {
Service.Start();
}

Where ServiceToWatch is the name of the service you want to watch if running or not
