Problem restarting a windows service with ServiceControlleri need to restart a windows service made with c# when an fixed event is raised. So to test it, I've added a servicecontroller to my service, and in the creation method, i've created a new thread to try to stop it. This is my code: public Service1() { // This call is required by the Windows.Forms Component Designer. InitializeComponent(); log = new EventLog("Application", ".", "ServiceTest"); _timer = new Timer(new TimerCallback(OnTimer), null, 20000,0); } private void OnTimer(object state) { try { log.WriteEntry("Timer"); serviceController1.Stop(); log.WriteEntry("Stopping"); serviceController1.WaitForStatus(System.ServiceProcess.ServiceControllerStatus.Stopped); log.WriteEntry("starting"); serviceController1.Start(); log.WriteEntry("Restarted"); } catch (Exception ex) { log.WriteEntry(ex.ToString()); } } When service is stopped it doesn't start again, what's the problem? Can you help me? Thanks! The issue is when you service stops, it is stopped. The code is stopped and
therefore never calls the start command. You need to call some other program to stop and resart the service.

You need another program to stop and start services. I'm not clear on why you need to restart a service anyway, services are invented to run from boot to shutdown time, and should only restart when a catastrofic failure prevents the service to continue it's tasks. In that case the service can be set-up to restart under control of the SCM.

Do you get any error? Does the service do logging? I have a similar situation, I have a service that create a TCP Listener in a worker thread of course, if you stop and restart it right away the worker thread (or at least the port ) is still active and you get error. -- Show quoteHide quote-- Ignacio Machin, ignacio.machin AT dot.state.fl.us Florida Department Of Transportation <sergio.call***@gmail.com> wrote in message news:1158926326.240038.85000@d34g2000cwd.googlegroups.com... > Hi Everybody, > i need to restart a windows service made with c# when an fixed event is > raised. > So to test it, I've added a servicecontroller to my service, and in the > creation method, i've created a new thread to try to stop it. > This is my code: > > public Service1() > { > // This call is required by the Windows.Forms Component Designer. > InitializeComponent(); > log = new EventLog("Application", ".", "ServiceTest"); > _timer = new Timer(new TimerCallback(OnTimer), null, 20000,0); > } > > private void OnTimer(object state) > { > try > { > log.WriteEntry("Timer"); > serviceController1.Stop(); > log.WriteEntry("Stopping"); > serviceController1.WaitForStatus(System.ServiceProcess.ServiceControllerStatus.Stopped); > > log.WriteEntry("starting"); > serviceController1.Start(); > log.WriteEntry("Restarted"); > } > catch (Exception ex) > { > log.WriteEntry(ex.ToString()); > } > > } > > When service is stopped it doesn't start again, what's the problem?

Last day at late hour i get the same conclusion :( , a service cannot be restarted himself.

How would you think > serviceController1.Start(); could ever be reached? Not at all, I did not read the OP correctly, I assumed he meant from another app, (in my case it's the user manually )
