question in regarding to resolution of domain name

Hi Guys,

Just a quick question, i don’t know if this is because of pro-site plugin or the setup wp multi site. The problem is this:

Case 1. http://www.abc.com – resolves correctly to the main site.

Case 2. http://abc.com – resolves to http://www.abc.com/prosite/?action=new_blog

Case 3. http://anything.abc.com – resolves to /prosite too (if there isnt blog named anything)

Shouldn’t Case 2 & 3 resolve back into the main site instead of /prosite?

In my DNS editor:

abc.com.	    14400  IN  A             123.345.66
www.abc.com. 14400 IN CNAME abc.com
*.abc.com 14400 IN A 123.345.66

Any thoughts?
