I want to be a Telnet Server, but i couldn't troubleshooting that why other computer on my LAN couldn't connect to me. I went these same steps on other computers but there were no problems to connect them and i can telnet to them.

1) i turned Telnet Client and Telnet Server features from "Control Panel\All Control Panel Items\Programs and Features"
2) then i enabled TELNET service from Services.msc and set that to Automatic.
3) also i enabled Telnet Server option from "Control Panel\All Control Panel Items\Firewal\Advanced settings (Inbound Rules)" and allowed the connection.
4) so i started Telnet Server service from CMD using "net start telnet"

then i tried to connect my Telnet Server from other LAN Computers. but it said:

Connecting To not open connection to the host, on port 23:
 Connect failed

How can i Fix this problem ?
I'm using Windows 7 and Avast! Anti-virus and Avast! internet security.
note: I did these same steps on another LAN computers , so i could connect to them.

can you try netstat -n -l in cmd to see if you listen on port 23? – mirkobrankovic Jul 2 '13 at 11:37
The parameter " -l " not working. i can connect to my telnet server using this computer, but others can not connect ! also i scanned from other computers and i find out that 23 port is not Actived (or allowed) . – Amirreza Nasiri Jul 2 '13 at 11:44
I strongly suggest not using Telnet, even if it is only in the LAN – the Windows Telnet server is also not maintained anymore, so third-party alternatives like WinSSHD may be more reliable as well. – grawity Jul 2 '13 at 11:45
@grawity, Security is not important on my LAN Network. because all of computers are in my control. – Amirreza Nasiri Jul 2 '13 at 11:49
@AmirrezA_Nasiri: I was not talking only about security. – grawity Jul 2 '13 at 13:04
