>>>>If you want XP machines to access a shared config file, it'll have to be hosted on something still running SMB1. That could be an older/legacy server, a repurposed XP workstation, or some sort of Linux/Samba host. Some routers allow plugging in a USB stick to be shared via SMB so you may already have that capability in place. Otherwise something like a Raspberry Pi 3B with case and power supply can be had for less than $100.

>>>Thanks Naoto and Al. I suspected that the XP machines might be a problem. Thanks for confirming that. I'm afraid to say that we're probably going to have to live with the risk. I guess we could use an ini file on the server that would point to a SQL Server that would have the same data in the same structure. But that would be a lot of work on our part.

But does VFP use SMBv1 for everything like Copy File or low-level File IO? And you could instantiate that COM fileobjectsystem or whatever it's called.
