Setting up your Internet Address is the next very important task included in SBS 2008 Getting Started Tasks.
Based on the Public Domain name that you provide (Internet Address), the Wizard configures Remote Web Workspace, Microsoft Exchange and Sharepoint Services. It is important to note that you have to be careful, when choosing the name because changing it is not that easy. Though you can run the Wizard again, and specify a new name, you will not be able to change automatically the Sharepoint Services configuration. As a result, you will lose access to the internal web site in Remote Web Workspace.

Next, we will configure and test remote desktop connection over RDP 6.1 to the SBS server.
Finally, we will configure an Outlook client for Outlook Anywhere and we will test the connection. Note, that all the tasks described are performed on an external machine the way you will perform these tasks in real life – from home or a remote location.
