I took the 291 today, unfortunately, I didn't pass it

. Sad say. But I did learn that I SUCK in these areas: "Implement, manage, and maintain Name Resolution" and "Implement, manage, and maintain Network Security". (I'm under 1/3 on both these graphs *sigh*)
I was going to ask for some good, thorough study materials that would help me become better at them. Also, I have a vmware team set up that has 2 DC's, 1 RRAS, and 2 XP clients. any scenarios that could help me experiment would be helpful.
ANY information would be helpful

.
Thanks
