Unfortunately FIPS did not help, neither did the registry hack in [3]
above. There is a bug somewhere in the Windows/Intel driver mix, but
I'm not going to waste any more of my time trying to solve their
standards (in)compliance.

I tend to try the strongest values I can get to work, and in this case
a server key using secp384r1 will still work while I need to support
Windows clients. But then again maybe that's why I keep having odd
things go wrong that Google can't help solve ;)

Thanks everyone for your help
