What would be the best course of action for an MCSE in NT 4.0 to take? Upgrade to 2k, or 2k3, or even both? I'm looking to have the next cert last long w/o worry of upgrading for a while and also be deemed as an asset to the majority of companies out there today. I know there is things like degrees and whatnot but I'm just talking microsoft certs here. It seems like if I had upgraded to 2k that I would not have been able to enjoy it as long as I did when I got 4.0. They keep releasing operating systems too fast.
