Does it successfully connect to any other Win10 machines in the same
domain? i.e. is it just this one machine, or something more generic?

I wonder if it might be due to the NLA authentication mechanism (or I might
be clutching at straws here, just from the NLA strings above).

A thread here has some more discussion.. it's not the same problem you are
having, but contains some pointers to other resources on the subject, if
that is indeed where the problem lies:

Or perhaps

Hope that helps, or at least gives some pointers..
