Yes (assuming you mean via the security dialogs). You normally change
the owner of the database object, by creating a new mdb while logged in
as the user you want to own the database.
If you need to change the owner, you'd create the new database, and then
import all the objects from your old database. The permissions won't
travel with the import, so you'd use a utility such as Jeff Conrad's to
transfer the permissions...
