But you could provide us CDiag log for Laptop, instead of for TARDIS_2 twice.

I wondered when I'd get caught out with that one! here's CDiag log for
Laptop:-

Hope it helps.

Thanks.

That it does. The problem - and it's symmetrical - is between LAPTOP and
TARDIS_2. Neither can access the other, in any of 4 tests each. Look at CDiag
for LAPTOP, Target TARDIS_2. Look at CDiag for TARDIS_2, Target LAPTOP.
# Ping by name. Name resolution problem.
# Net View by name. No display (you'll probably see errors in the command
window).
# Ping by IP address. Request times out.
# Net View by IP address. No display (you'll probably see errors in the command
window).

With pings being blocked, both ways, this points to either a physical (cabling /
router) or logical (firewall) problem. Let's test logically, and do this very
methodically please. Read thru instructions first.
1) Swap router ports for 2 cables - say NUMBER_1 and LAPTOP. See if the problem
moves.
2) Swap router ports for NUMBER_1 and LAPTOP back, then swap NUMBER_1 and
TARDIS_2. See if the problem moves.
3) Swap router ports for NUMBER_1 and TARDIS_2 back, then swap Ethernet cables
between NUMBER_1 and LAPTOP. See if the problem moves.
4) Swap Ethernet cables for NUMBER_1 and LAPTOP back, then swap NUMBER_1 and
TARDIS_2. See if the problem moves.

Tests 1 - 4 will identify either a router port or Ethernet cable as the problem.
If no changes are observed from any of the 4 tests, then the problem will be a
firewall. Or possibly a LSP / Winsock problem, but with the symmetry, I don't
believe that.

If it's a firewall, we'll think of some more tests. Just do this very
deliberately.
