Hello,
Thank you so much for the inputs. I just contacted my hosting provider and they told me that hey do not support ASP.NET as there hosting is all done on Linux based servers. This is a start to eventually get there!
And yes, my default (home page) is default.aspx for the .net web site, but this is at the end of an other html website.
Ex: http://www.domain.com/default.aspx
I guess I just need to find an other host provider for now and take it from there.
