Good Question.

Well, as I stated, I am not a network guy.

Many moons ago, we had a consultant in to look at products to push out software and updates. We got the Altiris eval. After a while, he recommended that we purchase this, so my boss did.
Anyway, to make a long story short, they (our network people), never got it to work right. So they wanted it clean off the machines. I do not know all of the details. But that is the story in a nutshell.
