VS2010 getting default web page in visual Basic

I have   www.mydomain.com/mydefault.aspx
That's OK.
If I put www.mydomain.com, I get another page which is located
in  Views/Home/Index.aspx  ( This was a page I did earlier and I cannot get rid of it which I was trying to use
a LOGIN.)   I no longer need the LOGIN.
Question   How can I get    www.mydomain.com/mydefault.aspx and www.mydomain.com  to show the
same web page? (ie my visual studio 2010 mydefault.aspx)
I tried setting "mydefault.aspx" on the server, but that did not work.
TIA
