It's been a pain in our ass... a mini Y2K of sorts. We've patched up/updated just about all our servers, including Exchange, Windows, and Unix... under our AD domain. Those Divisions under their own AD are also updating, but we can't control them, so... who knows? But, yeah, it has been a major pain. We also use Decru dataforts for encryption, and those have had to be updated. Yuk... We'll see what happens on 3/11.
