Experience is more valuable
I have experience in NT as well and Win 2k... not enough experience though. I am an MCSE on win2k and it is not really playing into things except making my resume look nice.
I got certified right out of school and only right then because there were no jobs available just then... but I would have certified in 2k anyway.
I am glad I got the cert because it shows that I can use the product, but I am still waiting to get a shot to get real experience...
