Yes, that seems more likely.

I think Windows can be a decent platform for light industrial applications - which this system in particular was. The problem is all of the partners and suppliers were either stuck in the past, or had weird ideas.

The parent system was *nix based, but there was a flaw in a communications protocol that lead to the channel bouncing between two boxes, and eventually bringing down the parent system.

My lesson from that was that you can have flaws on any system, no matter how solid the OS.
