I am working in SharePoint 2010.
Site Collection feature: SharePoint Server Publishing Infrastructure Activated
When I am creating a couple of new subsite with Team Site template.
Mostly new subsite created with default home page is Home.aspx (wiki Page) sitepages/home.aspx.
Sometimes new subsite created with default home page is the default.aspx (WebPart page) web page in the virtual root of the site.
What is the reason team site created with a default home page is default.aspx?
