title: Telnet is not recognized command when cmd.exe is started from Process.Start in C#
body: <p>I have already switch on the telnet option on control panel - program/features.
  Though telnet worked fine manually, but when I run below from my C# library, I am getting this error : </p>
  
  <blockquote>
    <p>"'telnet' is not recognized as an internal or external command,
    operable program or batch file."</p>
  </blockquote>
  
  <p>This is the code I use to start Telnet:</p>
  
  <pre><code>Process.Start("cmd", "/k telnet")
  </code></pre>
  
  <p>What makes the difference between this and running it from the command prompt manually and how do I overcome this difference?</p>
