I'm not speaking from personal experience either, sorry if I seemed to imply that. I just meant it as a general comment with regards to anything that the military does. There is so much red-tape surrounding procurement, implementation that I wonder if they are agile enough to be on the cutting edge.

I don't mean to diss W2k in general, Its an OS that is well understood by now - weaknesses, mitigations, etc. Slowmoving entities like the government accrue so much cruft that it makes it exceedingly difficult to move to newer (and possibly better) platforms to take advantage of newer security tech.
