I understand where you are coming from, you have to earn a living and
you have to do what your customer wants. You can advise till you are
blue in the face, but sometimes the customer just doesn't hear you.

Unfortunately, this isn't a rare occurrence and it isn't only
customers that don't want to invest in new equipment or software. I
once had a discussion with a software supplier about upgrading their
main package to run on Windows 7 (this was about 10 months before XP
went EOL), His reply was something along the lines of 'Don't bother,
Microsoft wont EOL XP, and if they do, you can still use it'. Look
where that got us, 'wanacry'

I almost suggested doing this when you said there was only 5
machines, It is probably the best thing you can do. Your main trouble
was that you went with a PDC rather than an AD DC, but for 5 machines,
either was overkill, especially if they are all in the same location.
