SOLVED: "allow incoming echo request" greyed out. enabled. can't
disable it

a solution is to go to the windows firewall, choose "file and printer
sharing", and uncheck TCP port 445.

if you uncheck the "file and printer sharing" entry itself, it doesn't
solve it !

I haven't looked into the meaning/famifications of whether an item is
listed or not, checked or not. Or why F n P sharing was even listed,
considering I had uninstalled it, and even disabled NetBT, to close
some ports like 139 as described by the petri article. But anyhow,
that works, .

This solution was from

I found it once and almost didn't find it again, there are many
answers that just talk of disabling file and printer sharing, but that
didn't work for me. This did.
