It's almost never about server capacity. It's usually about who's maintaining them, who controls the updates and versions of software on there, and which dept the server's billed to. All stuff that's reasonable for things of a certain size, but unreasonable for things too small or big to fit the process will.
I would love to see a study of how much IT spending in general is just for tools to work around corporate bureaucracy. I suspect the figure would be staggering.
