I appreciate your help but the program just opens an empty command window, does nothing and closes.
Process runServer = new Process();
ProcessStartInfo CMD_commandServer = new ProcessStartInfo();

//CMD_commandServer.CreateNoWindow = true;
CMD_commandServer.WindowStyle = ProcessWindowStyle.Hidden;
CMD_commandServer.FileName = @"C:\Users\nirf\Downloads\iperf\iperf.exe";
CMD_commandServer.Arguments = "-s -D";
CMD_commandServer.UseShellExecute = false;
CMD_commandServer.RedirectStandardOutput = true;

runServer.StartInfo = CMD_commandServer;
runServer.Start();
runServer.WaitForExit();

Process runServer = new Process();
ProcessStartInfo CMD_commandServer = new ProcessStartInfo();
CMD_commandServer.CreateNoWindow = true;
CMD_commandServer.WindowStyle = ProcessWindowStyle.Hidden;
CMD_commandServer.FileName = @"C:\Users\nirf\Downloads\iperf\iperf.exe";
CMD_commandServer.Arguments = "/c START iperf -s -D";
CMD_commandServer.UseShellExecute = false;
CMD_commandServer.RedirectStandardOutput = true;

This makes the program to freeze

I think your input regarding the CMD is correct but if I remove the "new ProcessStartInfo("CMD");" the code just crashes (win32exception was unhandled -- The system cannot find the file specified ) or freezes

thanks for your help. I have to run the iperf process twice because it's a server client networking test tool. and the program(iperf) does not work with just arguments.. you have to open a CMD and then execute it.
