SBS 2008 - Sharepoint 3.0

An interesting quirk in setting up SBS 2008. If you try and add users before running the 'Set Up Your Internet Address' Wizard, when you subsequently try and run the wizard, it fails; true to MS form, it doesn't give you any reason for this failure.

In the System Event Log, it coincides with the Event:

<:event xmlns="http://schemas.microsoft.com/win/2004/08/events/event">A Google search may lead you to believe that any one of a number of Hotfixes are required, followed by running the 'Sharepoint Products and Technologies Configuration Wizard'. In actual fact, all that is required is to run this Wizard in the first place. Once compelted, you can run the Set Up Your Internet Address Wizard and it completes sucessfully.
