NOTE: This article will assume that your site is configured to use ASP.net v1.1 which is the default setting with all new accounts. If you're unsure what version of ASP.net you're using with your site you can adjust it using the control panel.  This article also assumes that we'll be creating a new SQL database and that you have SQL databases available in your SQL database quota, if you require an additional SQL database you can add this through the control panel prior to following through this article.

As a final step open a web browser and browse to the location you installed DotNetNuke v3, this will run the automated DotNetNuke installation wizard that will finalize the installation of DotNetNuke in your website and once completed you should be able to log into your DotNetNuke portal and customize it.
