Subdomain dashboard 404

Hi, I’ve just installed the WPMU following the codex, I’m using subdomains.

However, I cannot access dashboard of the subdomain, it gives me 404 error, also when I try to go to the subdomain, it too gives me 404.

I use custom template plus I have Twenty Twelve enabled for network.

Wildcards *.domain.com are allowed with my hosting provider and active.

My .htaccess is this copy pasted from when I installed it.

RewriteEngine On
RewriteBase /
RewriteRule ^index\.php$ - [L]

# add a trailing slash to /wp-admin
RewriteRule ^wp-admin$ wp-admin/ [R=301,L]

RewriteCond %{REQUEST_FILENAME} -f [OR]
RewriteCond %{REQUEST_FILENAME} -d
RewriteRule ^ - [L]
RewriteRule ^(wp-(content|admin|includes).*) www/$1 [L]
RewriteRule ^(.*\.php)$ www/$1 [L]
RewriteRule . index.php [L]

Should I just wait for the DNS to update or is there a problem I’m not seeing?
