| I am running 2k server with Telnet services disabled. Authenticated users are still able to telnet the server. How can I stop client from telnetting the server?
Thanks | |

Its strange, but tell me if i am wrong; if you have disable or uninstall the Telnet Services, it is NOT possible for a client connect to the Server. Anyway, you could block the Telnet port (i think is 23) too if you want, using a firewall, for example. | |

| You can use port filtering and IPSec to filter out ports that you aren't specificly using.

| Are you sure Telnet is disabled and not just stopped? If just stopped they will be able to use Telent if the server is rebooted.
Is it Telnet that they are using to connect to the server or some other connection style?
Myself I hate Telnet and block that port immediately when I build a server unless Telnet is a real necessity. | |

There is some other service or application running on your machine that is listening on port 23 and (possibly) emulating a Telnet server. (Trojan Horse alert if this is the case.)
The only other explaination is that your Telnet service isn't really disabled. | |

| do a netstat -an on your server to see what ports are open. If port 23 is in fact open then get a tool that will map open port to executable, eg fport. |
