How to remove index.php from codeigniter 2.0.2

[eluser]mi6crazyheart[/eluser]
Here is my current .htaccess

Code:

<IfModule mod_rewrite.c>
    RewriteEngine On
    RewriteBase /vb/

    RewriteCond %{REQUEST_URI} ^system.*
    RewriteRule ^(.*)$ /vb/index.php?/$1 [L]
    
    RewriteCond %{REQUEST_URI} ^application.*
    RewriteRule ^(.*)$ /vb/index.php?/$1 [L]

    RewriteCond %{REQUEST_FILENAME} !-f
    RewriteCond %{REQUEST_FILENAME} !-d
    RewriteRule ^(.*)$ index.php?/$1 [L]
</IfModule>

& my problem is if i remove index.php from url like following example..

Code:

http://localhost/vb/account/forgetPassword

It's not working. Showing 404 file not found error.

But, when i include index.php as in following example in the url

Code:

http://localhost/vb/index.php/account/forgetPassword

It's started working.

I've also checked my apache for mod_rewrite setting & i think mod_rewrite has enabled. Here is a screen shot of my apache2handler config which i got by using php's "echo phpinfo()". I really don't know it's a right way to check for mod_rewrite enable or not but, from some web tuto i got this technique.
