Bret,
Exactly! These are the methods I have used in the past with a great deal of success. So, I will try to implement and illustrate for the students.
However, now that we have had this discussion, I think the best method is to just create a completely new tempdb, wich is what Mark was suggesting.
It may take a couple of weeks to get this done, as I have other priorities and challenges to attend to, but I will definitely report back on my results and post the corresponding code.
Regards,
Jean-Pierre
