Moodle networking (MNet)

Dear all,

I am new in moodle. i download moodle and installed in to my machine. which is basically linked to the LAN network. (operating System XP) .

after installation i was able to access my moodle through calling by http:// localhost. but my problem is when i changed wwwroot (located in config.php)in to my machine's IP address i was not able to access it through even using my machine. it show "cant find" error massages. and i wanted to access it through other machine. but couldnt.
