WordPress wont allow me to use subdomain on my site

Hey Folks,

I have a domain hosted at godaddy and on its root, wordpress is Installed. The blog works just perfect and i tried to install gallery2 on one of its subdomain. But something is just messed up with .htaccess that the subdomain becomes inaccessible using photos.mysite.com, however i can use it using mysite.com/photos.

I wonder how it is done and how i can i fix this. It is worth mentioning that gallery2’s root folder has an index.php which redirects to main.php and the subdomain folder(photos) doesn’t have .htaccess file.

The root has an .htaccess file which reads :

# BEGIN WordPress
<IfModule mod_rewrite.c>
RewriteEngine On
RewriteBase /
RewriteCond %{REQUEST_FILENAME} !-f
RewriteCond %{REQUEST_FILENAME} !-d
RewriteRule . /index.php [L]
</IfModule>

# END WordPress

Thanks in advance
Cheers!!
