Select Application Management and then create or extend web application
Select create a web application. To create a new web application you need to select a port number. MOSS will assign a unique port but I tend to find its best to plan this out before hand. Then assign rights. Also MOSS gives the database an impossibly long name which can make backup confusing so I assign a real name.
This process has created a Application, but a Web Application is empty. So you have the option to create a high level site collection.
To create a site collection you assign a template and administrators. If you don't assign yourself as an administrator you won't have access. In this case we make a collaborative portal.
This then create a top level site collection.
