Do anyone know how i can make a web appcation acccessible from other system on my network.

If its on the same network then it should be accessible. Just type the computer name on your browser and the file. e.g http://compname/program. where compname is the computer name and the program is the name of the web folder. P.s note the the systems must be on the same network and the same workgroup

well, like the otha guy said, just type the i.p address or the name of the system which is the server (make sure ur LAMP ) is on and the folder were the progammm resides and "VIOLA" , your application will run on the network

e.g

http://192.188.18.1/myapplication/index.php or http://mysystemname/myapplication/index.php

where
192.188.18.1 and mysystemname are the names of the server., myapplication is the name of the contaning folder , and ofcourse index.php is the home page of your application.

This shud work, hth.
