Process.Start() not started...

Have you ever checked your server's task manager after clicking your web page to see whether or not the process have started ;) ? I hope you will find your solution from the following link.

3) exe file placed in shared folder for all users..
4) I try overloaded with username, pass, and domain... nothing happend

Thanks Nick...

P.S. This file, which I try to start actually loaded into memory and is currently working, but I need that when run it executes the commands from the command line...

Could you provide a small sample program that demonstrates your problem? When you add more info, make sure to edit your original question rather than adding an answer. This seems to work for me:

static void Main(string[] args)
{
	string str = System.Reflection.Assembly.GetEntryAssembly().Location;
	if (args.Length == 0) System.Diagnostics.Process.Start(str, "hello");
	System.Threading.Thread.Sleep(5000);
}

When you run that console application, it will launch a second instance of itself and that second instance will detect the command line argument, which it will interpret as meaning that it should not launch any more instances of itself.
