I'm trying to start a process on a remote machine. I'm using OpenSCManager(), CreateService(), QueryServiceStatusEx() and StartService() API-s. I'm able to successfully install my process as a serice, but when i'm trying to start it, StartService returns with errorocode 1053 ("The service didn't respond to the start or control request in a timely fashion."). Can anyone help me to solve this problem?
Thanks in advance!

I think you are missing a key component here: starting Service Control Dispatcher. As stated in the documentation you have to start the service control dispatcher in order to enable Windows' Service Control Manager (SCM) to send commands to your service (like SERVICE_CONTROL_STOP for example)
Starting the dispatcher is done as follows:
SERVICE_TABLE_ENTRY (look at MSDN library) containing your services' name as well as its Service Main Function (wich is different from your ordinary main method!)The background is that every service is being started via SCM, that waits for the service to start its Service Control Dispatcher in order to receive its commands...
I see another problem in your code: you're trying to install your service everytime it's being started! You'd better check for appropriate command line arguments to determine if the service is either going to be installed or started!
