Simply done - NFS Share on Windows
If you want to share something over the network at home there are a number of things that can go wrong.
Do you do name resolution or do use use IP addresses to access your devices? If you are, are these static or can they change?
That is just one of the things and I have no idea what you are doing... and none of it is really related to Kodi.

So my suggestion is this, share a folder on your new computer and try to access it from the old computer.
Search online using your favorite search engine and select a how to guide and try to follow it, when you get that working.
Try to config you box the also access that folder on your new laptop.
This way you will learn about networking, user accounts and permission - all vital to sharing data between computers and devices.
I'm sorry I cannot be more specific, but there are thousands of great guides explaining this that I found by just doing a simple google search like this:
