Hi vipmedia,
If you upload index.html this will show up when you go to domain.com instead of domain.com/index.aspx showing up. Note though that the home page index.aspx will always be active though.
One thing that you can do though to prevent duplicate content is to simply change the title, keywords and description tags so they are not the same on both pages. Also if you are using any text to describe your site, make sure that text is different on both pages.

As an alternative, you could use the page redirect function to have indes.aspx to index.html, thus a single unit of content on the index.html page avoiding penalty.
