I have a HTPC with XP (~ see below) and I just installed Kodi on a Raspberry Pi (LibreELEC). A quick try with SMB didn't work, and I thought I recalled that WannaCry caused Microsoft to disable SMB, even on XP (my machine used the POS hack, so I was getting updates until recently). [EDIT: comments below suggest SMB was patched, not disabled]
So I thought I'd look at NFS, but I'm not sure how to get that installed. It seems that the "Windows Services for UNIX 3.5" might have worked, but it's no longer available anywhere that I can find.
Is there a good way to allow media on an XP machine to be used by a Kodi install across my home network?
~ Yes, it's unsupported, no, I'm not going to "upgrade" it, it's working fine, and it's on a separate network segment.
