Unable to change Telnet authentication method

Running Windows 7 Professional, I am unable to connect to client computers on my LAN through Telnet.  Telnet server and client functions are enabled, and the Telnet service is running.  When I attempt to connect to a client computer, after the password warning prompt, I'm told that Telnet is configured to use NTLM authentication only.  So I tried a command prompt, with
tlntadmn config sec +PASSWD
and got "the settings were successfully updated."  But the same thing happened  (NTLM authentication only) when I tried to Telnet to the client.

Any anti-virus or third party firewall software installed in client computer?

Yes, Norton Internet Security.  However, I  used  to be able to Telnet to these clients, and I can still share files with them across our Windows network.

Sorry, I misunderstood the purpose of the tlntadmn config sec=  command.  I was trying to apply it from the computer which is originating the telnet connection, and I needed to apply it to the computer which is to receive the connection.  Issue is resolved.
