No. Ping is an internal function in TCP/IP stacks. It is based
on ICMP and does not use UDP or TCP services.
tcp/echo and udp/echo (port 7) are diagnostic services that have
nothing to do with ping. They are disabled on most machines, for
security reasons.

If the PC is configured to reply to requests on that port, yes.
But this has nothing to do with ping. To find out whether
tcp/echo works try
try [
a: open tcp://machine:7
]
and check the result for an error.
If no diagnostic services are configured then just install an ftp
server (e.g. wu-ftpd) and try to connect to that. Or just start a
REBOL background process on your wife's PC that listens on
a port, e.g with
a: open tcp://:12345
Just pick some port number and then try to connect to that. It does
not matter what the server does as long as it is listening on some
known port you can connect to.
