Change or set Active Network

I have googled and checked the forum but I can't seem to see anybody else having this problem.

I have a simple network comprising of three PCs on a single router.
One PC runs Win7 and acts as a file server to the other two PCs.
The two PCs are running Win10 latest creator edition.
This is what the Active Network settings looked like on the two PCs.


The HomePrivate network "belongs" to the Server.

This week I had to replace one of the PCs and this is what its Active Network settings look like.
So my question is how do I get the new Win10 PC to see and join the existing network rather that a new one belonging to the router?
Thanks

It would be a whole lot more helpful if you showed the network adapter properties, for what the IPv4 settings are. You have multiple networks set up, which leads one to believe that you are using Static IP's, instead of letting the gateway hand out Dynamic DHCP IP's.

Thanks.
Here are the two configs:
