Microsoft Certification

Hi Guys

I really need so advise on the best way to go. I am going
to put myself though this but am not sure what way to go.
Do you have any advise on this?. As a start what exam,
shall I choose, exam 70-270 (configuring and administating
XP) or 70-210(Configuring and administrating windows
2000), I am not sure. I have been told the self paced
study material for the windows XP exam is rubbish, is this
true?. Otherwise I was thinking this was the best way to go

I would really appeciate any advise you professionals can
give me on this.

Thanks for you help in advance

Cheers

Martin
