I have Windows 7 on my computer at work now. Yeah, I know, finally. One thing I discovered recently was Telnet doesn’t work from the command prompt? I received the following error: “'telnet' is not recognized as an internal or external command, operable program or batch file.”
From what I have been gathering, Microsoft disabled this feature by default and did so with Windows Vista as well. I don’t’ use telnet that often but it can be handy when trying to troubleshoot ports through firewall if nothing else.
Telnet in Windows 7 can be enabled by going to Start >> Control Panel >> Programs >> Programs and Features >> Turn Windows features on or off (you’ll find this link on the right hand side).
Check Telnet Client.
Telnet will work through the command prompt right away.
