[Thanks to Damian Leibaschoff for this tip]


 


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.”
