You need to understand DNS, but in brief, there's file in Linux called /etc/hosts, which you need to be root user to edit (like MS Admin user).
If you add the ip address and the machine name to the file on the client machine, then restart the network software or the whole machine, it should be able to find the webserver machine. eg
You'll need to be root to edit the httpd.conf file to add the website name.
