Hi Mike,

Go with your true gut and nuke those machines. Use it as the basis for a
few good discussions. Leverage the rebuild pain and you'll come away with
much more than a lab full of machines the *might *be clean.

1) Why is it that we usually nuke machines? (because we can't guaranty
cleanliness)
2) Why is it that we have that opinion for single machines but are willing
to compromise on a whole lab full?
3) What does "cleaning" do for your credibility (on that and other issues)
with all of the people you've been preaching "nuke" to?
4) How'd the image get compromised? (Maybe the most important question)
5) How do we know other images are not compromised?
6) Is the current deployment method still workable or does it need to be
revisited? (thin, layered, virtualized apps, etc)
7) Is all of the software necessary? (not a question that is usually easy
to ask politically but you may be able to get some mercy from fence-sitters
who might say, "Well, I guess I don't need that anymore")

Sounds good in theory, I know! :-)

Hard work. Good luck to you.
