do you have a telnet server running?
make sure that the firewall on the server you're trying to connect to has port 23 TCP open. (that's the telnet port).

After you practice a little with telnet you will want to start using Secure Shell (SSH) as telnet is not a secure way to connect. In the program PUTTY you can select to use SSH instead of telnet....However, like 'root' said, ensure you have the telnet server running.

By default Telnet comes disabled in Windows. Here is a link showing you how to enable telnet in Windows 7. I can get you other links for other OS's if you need.

If you are still having problems after you verify the telnet server and clients are enabled, I would shut off your firewall only if the device you are trying to telnet into is local and not over the internet. (Firewalls can cause many network tools not to function correctly even if exceptions are enabled) If it is local, make sure you disconnect your computer from the internet. However, if the device you are trying to telnet into is over the internet, then I would strongly recommend using a more secure protocol such as Secure Shell as telnet sessions are plain text and can be easily intercepted.

ok. once again. do you have the telnet server running?

not only is the telnet client not installed by default, but the telnet server is not either

Install Telnet Server

try connecting from the server to the server. then try connecting from the other machine


or, of course you could skip the telnet step altogether, (since that's insecure)

and go straight to using ssh
