I've written an installer that installs a windows service (A) that needs to start/stop another service (B). However, when A tries to start/stop B, I get this exception:
System.InvalidOperationException: Cannot open MyService service on computer '.'. ---> System.ComponentModel.Win32Exception: Access is denied
The installer installs the service as a local service, and it requests admin rights via the UAC pop-up, which I grant. I've also added an app.manifest file to the service that is set to ask for admin rights:
Yet I'm still getting that error.
This is how I start the service (stopping is the same, except it calls Stop, of course):
using (Mutex mutex = new Mutex(false, "MyServiceLock"))
{
mutex.WaitOne();
if (ServiceExists(serviceName) == true)
{
using (ServiceController serviceController = new ServiceController(serviceName, "."))
{
serviceController.Start(); // this line throws the exception
}
}
mutex.ReleaseMutex();
}
Why might access to this service be denied?
