I just uploaded and installed DotNetNuke to my web hosting company server using their instructions.  Everything worked fine except,  to access my new DotNetNuke site, I have to direct my URL to a sub directory.  Ex.  mysite/DotNetNuke/defaultpage.aspx.  The DotNetNuke files are in a folder called DotNetNuke_4 located in the Webroot directory.  My web hosting company says that I can not just move the DotNetNuke files into the Webroot folder because they need to be in an approot directory and the webroot directory can not be a approot directory.  So what I now want to know, is there a way to redirect the  default page in the root directory to the DotNetNuke folder default page? 

You can successfully move it to the root at GoDaddy there are tons of people that have done it.  I have done it once successfully, but then when I tried to upgrade DNN it busted it... so I had to go back to their install on a subdirectory.  There are forum posts and google pages about it, but most are outdated so I'm waiting for someone to pipe-in about the latest and best way to do it, but it is definetely possible.
