Getting Telnet to Work on the Live Cisco Rack.
Microsoft disabled telnet in Windows Vista (don’t ask why). They also removed windows hyperterminal in Internet Explorer 7. If you have either then please follow the below instructions and do not attempt to log into the rack until you have done this because your session will not work.
Enable telnet in IE7
Or even better:
If you are using Microsoft Vista, and you never enabled telnet then please follow below directions:
By default, the telnet program is not enabled / installed in Vista. To install it, follow the below.
1. Open 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. When a dialog box shows up, just confirm for the installation. After this procedure, the telnet command should now be available.
