You may not have much choice if you need to talk to riscos, but
Microsoft's advice is

Stop using SMB1.
/Stop using SMB1/
*STOP USING SMB1!*

Within a home network behind a NAT router, where presumably you trust
all your own devices it shouldn't be an issue, provided you don't allow
VPN access, or anything that could tunnel TCP ports 139 or 445

And now all the Win 10 machines are talking to one
another too.

Wouldn't explain why the Win10 PCs couldn't ping each other by IP addr,
the Computer Browser service (which relies on SMB1) probably explains
why they can now locate each other, but there are newer protocols ...


There are two entries in services.msc that begin
with the word "Function" that seem to have something
to do with name serving. With SMBV1 off, you could
try again with those "Function" ones running and see
whether the Win10 machines see each other. The "Function"
ones won't help you contact a WinXP box.
