By default, Vista doesn't install the Telnet client. The client is for text-based communication with remote systems.


You can install it by following these steps:

  1. Click Start then select Control Panel.
  2. Select Programs and Features.
  3. Select Turn Windows features on or off.
  4. Select the Telnet Client option.
  5. Click OK.
  6. A dialog box will appear to confirm installation. The telnet command should now be available
