Problem: If you want to define a static fully qualified domain name (FQDN) on your windows XP/Server 2003 machine, so that your computer does not contact a DNS server to resolve a particular IP address then you can do so by using the instructions explained below. Scenario: This can be useful on a number of situations one such situation is as follows. Let's say you have a web server hosting www.example.com and you want to add a new machine to this web address for load balancing purposes. Once you are done setting up the new machine you'll test it by using the direct IP address of that machine. You cannot access the new machine using www.example.com because every time you try that your computer will be forwarded to the old machine (whose IP address is stored in the DNS server). In this situation you can use the instructions below to give a static IP address (IP address of the new machine) to www.example.com, so that your computer connects with the new server (when you access it) using www.example.com.

Before you proceed, please note that this method may not work at all times because some websites hide their server information. Also, this method should be used to find out more about your site's security and should not be used for any other purposes. All the instructions below are tested on Ubuntu Linux Server but should work fine on other platforms running telnet.

I am going to show you how to change Apache's source code before compiling and installing so that it always shows a different name while using the technique described here. I have used Apache version 2.0.59 for this tutorial. Assuming that you have already downloaded the source code and extracted all the files in httpd-2.0.59, 'cd' into httpd-2.0.59 and use 'nano' (or your favourite text editor) to open the file (httpd-2.0.59/server/core.c) containing the Apache label.
