WINDOWS XP + WINDOWS 2000 + WINDOWS 2003 TELNET SERVER SETUP

WINDOWS XP + WINDOWS 2003 TELNET SERVER - SETUP(How to enable Telnet in WINDOWS XP + WINDOWS 2000 + WINDOWS 2003)
-----------------------------------------------
Windows 2003 comes with a telnet server that gives you a way to
access a DOS prompt from remote machines via telnet.

The following shows how to configure the windows telnet server
to work with any telnet client (even unix), and to be enabled
so that it comes up automatically after reboots.

Run these commands as administrator from DOS:

    sc config TlntSvr start= auto
    sc start TlntSvr
    tlntadmn config sec=-NTLM
    tlntadmn config mode=stream

Enable Secondary logon service in services.msc

That's it.

You should now be able to telnet to this machine from any windows or
unix machine, and login to get a DOS prompt. If you need to login
as a domain user, use the "domain\username" syntax when logging in, eg:

Welcome to Microsoft Telnet Service

login: mydomain\john
password:


WINDOWS 2000 TELNET SERVER - SETUP
----------------------------------

Windows 2000 (Professional, etc) also comes with a telnet server.

0) Login as administrator
