I just passed 2 hours ago with a score of 800.
I was really worried last night and this morning. I have 2+ years of Help Desk experience but I was scoring 60-70%ish on practice tests.
At the last minute, I started skimming through the MS press book. I think that helped a bit. I was able to get some key points that the Sybex book didn't really cover.
Resources used:
Sybex MCDST Deluxe (read 2 times)
Examcram 2 bundle (read 2 times)
MS Press book (skimmed through it in a store 2 hours before exam

)

Various practice tests and study guides
On the test, I had a lot of questions about permissions, DNS, and Remote Assistance/Desktop.
Now on to 70-272!
