Vista can't access Windows 10 share

I work with a company that has 5 computers with NO internet access. They are only connected to each other by a switch (no router).

4 run Vista (I know, not supported, but again, offline). 1 now runs Windows 10.

The addresses are in the 169.254 subnet. This has always worked, until we introduced the Windows 10 system.

I can ping the Windows 10 system, and the Windows 10 system can access resources on the Vista system, but the Vista system cannot access a share on the Windows 10 system. It says that the share is no longer available. The Sharing and Security are set to Everyone-Full Control.

Is there anything in Windows 10 that would block access to a Vista system?

Vista will require the Windows 10 PC to have SMB 1.0/CIFS Server enabled in Windows Features and the automatic removal of SMB1 disabled. By default the deprecated SMB1 is disabled in W10.

Turn Windows Features On or Off in Windows 10

THANK YOU! I knew it was going to be something relatively straight-forward. I hope to test this tonight
