Wp 3.0 Multi Domain (Url) Problem

Hey guys,

I have got some problems with WP 3.0 Multi Domain functionality.

Problem:

Server A
Domain: example.org

Server B
Path: example.org.example.example-server.org/
Wordpress: example.org.example.example-server.org/wordpress
WordPress-Adresse (URL) https://wordpress.example.org
Site address (URL) https://wordpress.example.org

Server A is configured to take example.org.example.example-server.org/wordpress to wordpress.example.org

Server B is configured to WordPress-Adresse (URL) and Site address (URL), to https://wordpress.example.org

So far it’s fine. I can connect to wordpress via wordpress.example.org

But now I want not only 1 wp-blog as subdomain of example.org but a few more.. so I decided to use WP multi blog.

My problem now is to make wordpress believe to be at subdomain.example.org (correct urls in frontend e.g.) and I don′t know how to configure this.

yours sincerly
Yattaa
