[arch-general] Got a problem with networking.

[mick howe]

Originally using the same account name/password on all systems but after
latest network issues started I changed passwords on win7 and arch.
Made some impact: arch to desktop win10 now works, Laptop to mapped arch
directory works,
Arch to laptop win10 no, win10 desk to laptop no, win10 lap to win10 desk no
Need to work out how to use wireshark/tcpdump when I can think again
