godaddy 404 Page Not Found

[eluser]waqas amad[/eluser]
hi i have the same problem on godady

i am not using any .htaccess file.

i have used separate files for admin and site. used default index.php for public site, and used admin.php with change path for admin folder .

in the config.php of admin/config/config.php i have used the following settings:

$config['base_url'] = "http://www.orientbs.com/premy/admin.php";
$config['index_page'] = "";
$config['uri_protocol'] = "REQUEST_URI";

and for public site i have used:

in the config.php of both site/config/config.php i have used the following settings
$config['base_url'] = "http://www.orientbs.com/premy/index.php";
$config['index_page'] = "";
$config['uri_protocol'] = "REQUEST_URI";

the public site working fine on godady, but the admin side giving error for 404 page not found, i have also tried .htaccess that shown in different disscussion boards,
i have also used this .htaccess file

<IfModule mod_rewrite.c>
RewriteEngine On
Options +FollowSymLinks

RewriteBase /premy

RewriteCond %{REQUEST_FILENAME} !-f
RewriteCond %{REQUEST_FILENAME} !-d
RewriteRule ^admin/(.*)$ admin.php/$1 [L]
RewriteRule ^admin/$ admin.php [L]
RewriteRule ^admin$ admin.php [L]

RewriteCond %{REQUEST_FILENAME} !-f
RewriteCond %{REQUEST_FILENAME} !-d
RewriteRule ^admin(.*)$ admin.php [L]

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

</IfModule>

link for public site:
http://www.orientbs.com/premy/index.php (work fine)

link for admin site:
http://www.orientbs.com/premy/admin.php (give 404 error)

on my local system it is working fine, i have also tried to change the "uri_protocol" to every option, but for admin site i am still facing error .
