>Here's something to consider....for the longest time I used NOLOCK for different scenarios, and while I never got that particular error, it does lead to result sets that might reflect incomplete update scenarios posted by others.

The Snapshot isolation level gives you the best features of a dirty read and a read committed (no locking and no concurrency issues) without the bad side-effects ( incomplete results and lockouts...and in your case, the error you received).
