Overwrite query for page template?

I have a function that is creating subdomains based on specific pages. So solutions.mywordpresssite.com is loading the content from http://www.mywordpresssite.com/solutions/. I’m doing this by overwriting the query_posts() and matching the subdomain to the subfolder. The problem is, solutions.mywordpressite.com still thinks it’s the homepage. It is displaying the correct content from /solutions/, but the template and other data is all being pulled directly from the static homepage. Is there a way that I can tell my subdomain to pull the rest of the data from the /solutions/ page as well?
