When you try to install SBS 2003 R2 you get a generic error:
When you review the R2_Setup.log you see the following errors:

This can happen if you try to install SBS 2003 R2 as a user that is NOT the built-in Administrator.
How can you tell if you are running as the built-in Administrator?
From a command prompt run:
NET USER <USERNAME> /Domain
(Replace <USERNAME> with the user you are currently logged in with).
The built-in Administrator will show the following as the Comment:
“Built-In account for administering the computer/domain.”
