First of all log time reader first time poster.
Just passed 70-271 on second attempt - first attempt was 658, second attempt 950.
The exam jitters hit me hard first time round but the second chance offer thing was nice from Microsoft.
Anyways figured I'd perhaps pass on a little information / tips that I found handy.
1) VPNs, VPNs, VPNs - I pulled a lot of questions on VPNs which tripped me up in the first attempt - went back studied them hard and blitzed the questions this time around
2) Installing XP - make sure you know your unattended installations via answer files network installations etc.
3) Don't panic =P If at first you don't succeed - grab a second shot for free offer and study your weak areas - the printout determines what you had problems with -go away study them - come back slaughter the exam
Anyways - just thought i'd throw my 2 cents in hopefully it helps someone. Onwards to 70-272.
