I disagree. It isn't that it works well but merely that it is there. In fact the majority of Windows networks both corporate and small business I can safely say that it barely works and is usually a mismanaged unpatched mess or filled with crapware. Occasionally there's a nice tight network (our operations guys run a tight ship which is cool) but the general case is a pit of incompetence.
The mantra among the consults I've met in the UK is if you're charging by the hour, do it in .Net on Windows. If you're charging a fixed rate, use Linux and Python.
I'm not suggesting there is anything better for an end user but I'm pointing out that it doesn't work well enough.
I still use it however and have a fondness. The accumulated knowledge of fixes is incredibly valuable.
