Stopping a windows service via program

Programmatically stopping a windows service in c# generates below listed System.InvalidOperationException

{Access is denied}

If i start/stop through windows interface then everything works fine! I'm an Admin user and running the service under Windows 7

If authentication is the problem ...

You can programatically control the user from which you're doing stuff with, using 

WindowsIdentity

and

[DllImport("advapi32.dll", SetLastError = true)]
private static extern bool LogonUser(...)

I don't know if that would work, but it could be worth a shot.

IntPtr token IntPtr.Zero;
LogonUser(username, password ..., ref token) //and some other parameters
var identity = WindowsIdentity(token);

using(identity.Impersonate())
{ 
    //do stuff here using another identity
    //find service and stop it
}

edit: This can be used for authentication on remote servers.

I'm not sure how you are trying to stop it, but I tried this on my system now, and this approach at least works fine:

var p = Process.Start(new ProcessStartInfo
        {
          FileName = "net",
          Arguments = "stop NameOfService",
          CreateNoWindow = true,
          WindowStyle = ProcessWindowStyle.Hidden
        });
p.WaitForExit(); //add this line if you want to make sure that the service is stopped before your program execution continues

This sounds like a UAC issue - try running the application which shall control the service as admin (right-click, "Run as Administrator").

Note that even an administrator account does not have full privileges unless you explicitly run applications in administrator mode - this was introduced for protecting the user from malicious software in Windows Vista and has been there since then.
