I'm struggling with starting a service from another application.

Ok, first, that's my starting point: I got a usual service wrapped into my own class which inherits from ServiceBase. Furthermore I got a ProjectInstaller instance, which inherits from System.Configuration.Install.Installer and takes care of installing my service on the system in the right way.

it's got these parameters:

serviceInstaller1.ServiceName = "NameOfService";
serviceInstaller1.StartType = System.ServiceProcess.ServiceStartMode.Manual;
serviceProcessInstaller1.Account = System.ServiceProcess.ServiceAccount.LocalService;

This ProjectInstaller output is installed through a usual C# .NET installation project.

The service is shown in the GUI list of services within system control -> administration -> services. But what I'm wondering about is that the service does not appear in the list of services, if I use the cmd.exe and type "net start".

That's waht I have so far. Now I want to start my service from another application. This application inherits from 

ServiceController

If I want to call now the 

Start()

method, I get an error telling me that the service could not be opened of the local machine.

I use the same Service Name as stated above. T'm confused about that, because I thought the service is installed correctly through my installer. Or does my application (and the cmd.exe too) does not have enough rights to access the service?

    Does the account the application runs under have permissions to start services? – Oded Oct 24 '11 at 12:33
  • it's currently the only account on the system having administrator rights, I guess it's allowed to start services, yes. Installing and Starting the service is done using the same account. – inva Oct 24 '11 at 12:39
  • Are you able to start the service manually? – Oded Oct 24 '11 at 12:40
  • yes, but only from the user Interface, not from the command line. Starting the service from the command line encounters an error telling me that the access is denied. – inva Oct 24 '11 at 12:43
  • starting the cmd.exe explicit with administrator right works fine. But I hope that there is a way to avoid the need of having administrative rights for starting a service?! – inva Oct 24 '11 at 12:45
  • Then you need to look at accounts and permissions. Access denied points to that. – Oded Oct 24 '11 at 12:45
  • hm, ok, maybe I shall point out that i'm using Windows 7. That means i'll have to say explicit using right click "start with administrative rights" that an application has administrative rights. thats a kind of tricky – inva Oct 24 '11 at 12:51

I found this article on stackoverflow. I think this answer posted there can be applied here too.

see the link below ServiceController permissions in Windows 7

I've run into this issue before, and it was permissions-based for me, too. I wish that error message was a little more clear.

I'd recommend taking a look at this SO article: C#.NET: Acquire administrator rights? - it looks like there's a good tutorial about upgrading to administrative rights provided in the answers.
