I don't use telnet but a friend of mine asked about it to play with some commands. I noticed that in widows 7 its not working, then i came across a short trick to enable it since it not secure thats why windows 7 disabled it also in case of vista but don't worry here is a small way:


1.Start

2.Control Panel

3.Programs And Features

4.Turn Windows features on or off

5.Check Telnet Client

6.Hit OK

Hope it may help you someday!
