I am trying to write a app and service which monitor a given set of services and a) makes sure they are running and b) based on certain criteria, restart them as needed.
I keep running into an access denied error.
If I simply iterate through the processes on the system, find the one I want like so:
foreach (ServiceController sc in ServiceController.GetServices())
{
if(sc.ServiceName == "MyServiceName")
{
sc.Stop();
sc.WaitForStatus(ServiceControllerStatus.Stopped, new TimeSpan(0, 0, 60));
sc.Start();
}
}
I get:
InnerException: System.InvalidOperationException
Message="Cannot open My Service service on computer '.'."
Source="System.ServiceProcess"
StackTrace:

at lib.ListServices() in D:lib.cs:line 552

InnerException: System.ComponentModel.Win32Exception
Message="Access is denied"
ErrorCode=-2147467259
NativeErrorCode=5
InnerException:
I have tried to impersonate a user, I have tried to do the same code from another service which is running as a system service. Neither of which have actually been able to affect the service. If its started, I cannot stop it. If its stopped, I cannot start it. I know this is all related to permissions I'm just not finding a mechanism that actually lets me control the service.
Any assistance would be greatly appreciated.
