Bob,
If you've done any networking work, you'll have occasionally run into a network
that works one way, but not the other. You have 3 ways to verify that the
problem is NOT physical.
1) Swap the 2 computers, end for end, so that Computer A uses the cable and
router port that Computer B was using, and vice versa.
2) Read the manual that came with the switch (what model??), and see if any
diagnostics are included.
3) Replace both cables and the switch (not guaranteed, as you could end up with
any one item defective too).
If you have connectivity one way, but not the other, I'd suspect that logical
(IP) connectivity is good.
If you have ANY remaining personal firewall or other security software on either
computer, remove it. Read thru some threads in MPWXNW, about personal
firewalls, if you don't understand.
Finally, check LSP / Winsock. If you just un installed anything, check it
again. Use all tools repeatedly, until all tools return negative results.
Please, don't post

without some way of backing that up. Preferably 400% of this incredible amount
of detail.

Again, do some more reading. It's there to help you.
