Help with NFS Client error: "Failed to connect to NFS WMI provider"

I'm having problems with NFS sharing. I'm running haneWIN NFS Server on my Win 10 64 Pro box, which I use as a media server. In trying to troubleshoot these issues, I'm trying very basic commands on my other main Win 10 64 Pro machine using Microsoft's built in NFS client (which until a few days ago was working fine). Here an example using the standard cmd shell (not PowerShell):

CMD> nfsadmin client \\192.168.10.104\
Reply: Failed to connect to NFS WMI provider

Can anyone help me understand that? Or perhaps a fix?

Thanks!

I wouldn't rely on Microsoft for this sort of thing. May be interested on what I touched on here.

I know this doesn't answer the question, it's just I never used M$ for networking file shares and what not. I don't trust it, and I know it'll just have me pulling my hair out.
