psexec c# to start remote process not working

Question

I am trying to kick off a bunch of processes on a remote computer connected to my LAN. I had code working to do the same thing on a local computer. However, that API didn't allow me to do this.

for (int k=1;k<=iterNum;k++) {

 argumvar="-c -i "+sourcePath + Convert.ToString(k) +
      "\\myProgram.exe /r "+sourcePath+Convert.ToString(k)+"\\"+nameonly;
 Process process = new Process();
 ProcessStartInfo psi = new
 ProcessStartInfo(@"C:\PsExec.exe",argumvar);
 psi.UseShellExecute = false;
 psi.RedirectStandardOutput = true;
 psi.RedirectStandardError = true;
 psi.RedirectStandardInput = true;
 //psi.WindowStyle = ProcessWindowStyle.Minimized;
 //psi.CreateNoWindow = true;
 //psi.Arguments = argumvar;

 process.StartInfo = psi;
 process.Start();

}
