Kelly - are you looking for a report that shows the Database Size listed in a configuration report table like that? You cannot do that - that was a terrible idea and should have never existed. SQL DB size should never have been a class property. It works on SQL 2000 because we never fixed that MP by deprecating those discoveries.
You can however, write a SQL based report with this information, but you would have to base it on a SQL query that is custom written.
