Questions like this show the incredible disconnect between HN and the widely deployed tech that the world depends on. The use case for Windows Server is running a centrally managed office: from operating your own certificate authority and deploying PC images, to managing resources like virtual desktops, print and file servers, all the way down to individual browser settings and even the ordering of items in the Start menu.

You can recreate Windows Server on other platforms by stringing together bits and pieces, but there is nothing that comes even close in terms of integration and how everything works together. Nothing.
