problem accessing virtual host from windows xp

i have apache running on my fedora machine. i have created virtual
hosts on that and i am able to access various websites hosted on
different virtual host from local machine. i have added these names
to /etc/hosts files in linux.
the ip address of linux is 192.168.0.3
and that of windows xp is 192.168.1

now the problem is that when i try to browse these sites from my xp
using ipaddress 192.68.0.3 in ie browser, i get the following error.
Cannot find server or DNS


can someone please help to access these sites from xp without using
dns


thanx in advance
