We recently migrated from SQL 7 to SQL 2000. In SQL 7 whenever a clustered index was rebuilt the NC would get rebuilt, but in SQL 2000 i do not see the NC being rebuilt. Atleast not in last 2 weeks of what i have seen. So is this an enhancement in SQL 2000 or does that mean the keys havn't changed to affect rebuild of NC?

Very good article and the dicussion is also providing lot of information.
