[AccessD] SQL constant harassment

I am doing a demo Access database against a SQL Server BE.  Access is constantly "harassing" me with 
pop-ups to provide log in information.  At odd times, not always.  But when it happens it is for 
each (bound) form getting data.  So a main form with subforms, and apparently even combo boxes, it 
will pop up the box to select the user authorized to do this.

What do I do to make this go away?
