Debugging WPMU

I am so sick of seeing this...

No WPMU site defined on this host. If you are the owner of this site, please check Debugging WPMU for further assistance.

I have done the edit DNS zone, added the virtual host to the httpd.conf, deleted my htaccess, removed the old wp-config file, and yet I am going around in circles.

Any help appreciated. Thanks in advance.
