wamp on LAN setup

today i was setting up kids channel local lan PMO Stuff. just for my memories
i started with installation of WAMP 2.0
then install joomla 1.0.15 and it worked perfectly.
then to make it available for LAN, i updated

configuration.php. changes made to that specific files were mentioned below find and replace “localhost” with “pc_name” in line...

apachee “httpd.conf” and replace server “name”:80 with my pc name and restart pc
it worked fine

update: 2010
i heard now there is a switch "turn online" which lets you acess this via lan card
also there is helpful post.
