Outer Join Challenge

I'm struggling with the creation of a SQL 2005 statement involving two
tables. I've simplified the situation below.
Table: Opportunity
Columns:
Name - always has a value
OpportunityID - key field link
Status - 0 or 1 for Open or Closed
Table: Activities
Owner - always has a value
RegardingObjectID - key field link
Status - 0 or 1 for Open or Closed
I am attempting to isolate those opportunities that do not have an open
activity. I thought an outer join would do the trick, and I would just look
for those opportunities with a null Owner. Below is my statement:
SELECT Opportunity.Name, Activities.Owner
FROM Opportunity LEFT OUTER JOIN Activities
ON Opportunity.OpportunityID = Activities.RegardingObjectID
where Activities.Status = 0
It seems as if the join is evaluated first before the filters, so that
opportunities that have no open activities are being dropped because the
link is pulling in the closed activities. In other words, the only results
that are returned with a null Owner are those that have neither an open nor
a close activity.
This is a SQL statement that I am going to use for a SQL Report using SQL
Reporting Services, so I think I need to accomplish this with one SQL
statement.
Is my only avenue to create a restricted view of the Activities table and
use that in my report?SELECT Opportunity.Name, Activities.Owner
FROM Opportunity LEFT OUTER JOIN Activities
ON (Opportunity.OpportunityID = Activities.RegardingObjectID and
Activities.Status = 0)
