70-291 Windows 2003 Network Infrastructure nightmare

I am taking exam 70-291 Windows 2003 Network Infrastructure for the third time this Saturday. The first time I took it I score 650. I took again last Saturday and scored 636. I seem to be struggling with DNS questions. I am using Transcender for test questions and the Microsoft press second edition book for preparation.
Any insight on how to conquer this beast will be greatly appreciated

I would say it sounds like you may want to use a different study material. I like CBT Nuggets.
The MS study guide and Transcender are fine for this exam.
Good luck
