The NT5 kernal is great but for the future I just don't see businesses hooking into .Net's propriatary network. I first looked to Novell 5.1 running 2000Pro as a replacement for NT4/98. However, after debugging the numerous cross-platform payloads of CodeRed.C from my system I've essentially washed my hands of MS.
What DEC, IBM and Apple were in the mid-80's MS has become now. It's retreating into it's own propriatary network like the previous did. It's successor will be the same to MS as MS was to those it previously vanquished: cheap, stable, easy to run, with the broadest application base -i.e. Linux. It's the same basic formula MS used, just via a different channel now.
I've pretty much decided not to bother with 70-240. I'm primarily a database developer these days and I don't really do "MCSE work" any more. And I haven't studied much, so I probably wouldn't pass. Maybe I'll do MCDBA next year.
