Multiple Sites on one WPMu install

I started trying Dr. Mike’s badass hack for Multiple domains with one installation using the Multi-Site Manager Plugin. I pretty much got everything working using Richard Bui’s tutorial of Dr. Mike’s hack. I’m left with one issue however: the domain set up fine and I modified the database tables to give me WPMu site admin access.

Additionally, I can setup new subdomain blogs through this new domain, i.e. etc., but when I click on them I receive the dreaded “server not found” error message. From previous experience I am assuming this is an apache issue that can be resolved with .htaccess. But I really don’t want to mess up the existing code in their because I have no idea when it comes to apache. Any tips or hints for how I might solve this?
