Windows 7 Telnet server configuration

[balubeto]

Hi

I have a computer with Windows 7 Ultimate SP1 64 bit called Pippo and I have enabled the Telnet server. Its configuration is:

C:\Windows\system32> tlntadmn

The settings on localhost are as follows:
Alt key associated with 'CTRL + A':         YES
Idle Session Timeout:                       30 minutes 0 seconds
Max. connections:                           5
Telnet port:                                23
Maximum number of failed login attempts:    3
End Task to disconnect:                     YES
Operation mode:                             Console
Authentication Mechanism:                   NTLM
Domain Defaults:                            Pippo
Status:                                     Running
C:\Windows\system32>

I have an other computer with Windows XP SP3 and I have enabled the Telnet client. Its configuration is:

C:\Windows\system32> tlntadmn

The settings on localhost are as follows:
Alt key associated with 'CTRL + A':         YES
Idle Session Timeout:                       30 minutes 0 seconds
Max. connections:                           5
Telnet port:                                23
Maximum number of failed login attempts:    3
End Task to disconnect:                     YES
Operation mode:                             Console
Authentication Mechanism:                   NTLM
Domain Defaults:                            Pippo
Status:                                     Running
C:\Windows\system32>

The two computers have accounts with different credentials.

If, by the Client, I write:

C:\Documents and Settings\Account_comune> telnet Pippo

This error is displayed:

Microsoft Telnet Client
The escape character is 'Ctrl ++'

You are sending information to a remote computer in the Internet Zone. This may not be secure. Send it anyway? (y/n) y

Telnet server could not log you in using NTLM authentication.

Login using your username and password

Telnet Server is configured to use NTLM authentication only.
Contact your administrator to enable username/password authentication.
Telnet Server has closed the connection

Connection to host lost.
C:\Documents and Settings\Account_comune>

How come? How do I display the Login of the Server?

Thanks

Bye

It seems like you are encountering an issue with NTLM authentication when trying to connect to the Telnet server from the Windows XP SP3 computer. The error message suggests that the Telnet server on the Windows 7 Ultimate SP1 machine is configured to use NTLM authentication only, which is causing the authentication problem.

To resolve this issue, you will need to address the NTLM authentication settings on the server side. Here are some steps you can take:

1. Enabling Username/Password Authentication:
- As per the error message, the Telnet server is configured to use NTLM authentication only. You need to enable username and password authentication on the Telnet server to allow connections from clients with different credentials.

2. Changing Authentication Mechanism:
- Check the Telnet server settings on the Windows 7 Ultimate SP1 computer to see if you can switch the authentication mechanism from NTLM to Username/Password authentication.

3. Domain Accounts and Permissions:
- Ensure that the account you are using on the Windows XP SP3 computer has the necessary permissions to connect to the Telnet server on the Windows 7 Ultimate SP1 computer.

4. Server Login Display:
- To display the login prompt on the Telnet server, you may need to adjust the authentication settings to allow for the entry of username and password when connecting.

Try adjusting the Telnet server settings on the Windows 7 Ultimate SP1 machine to allow for username and password authentication in addition to NTLM authentication. This should allow you to connect from the Windows XP SP3 computer using the correct credentials.

If you need further assistance with specific configuration details or settings, feel free to provide more information about your setup or any specific configurations you have in place on both machines.
