A Can Ping B, But B Cannot Ping A?

Oops again... Now I pinged B from B itself, then pinged B from A again and it
worked.

Can anybody point to where I should start looking - bearing in mind the thing
where when A opens B's SharedDocs it winds up looking at itself instead of B?

The little voice is possibly correct.
Do you have file and printer sharing enabled as a firewall exception on B
but not on A? The firewall lets everything out, but only certain things
in, so this would allow A to access B, but not the other way around.
Allowing ping in appears to be tied to file sharing - if I turn this
exception off and on, it also blocks or allows ping.

If you mean Windows Firewall|Exceptions|File and Printer Sharing = Checked, then
yes - both PCs have it checked.

I'm starting to wonder, however, if it's a Windows Firewall issue bc when I turn
Windows Firewall off on both PCs (Windows Firewall|Off (not recommended) =
Checked) the problem persists.

OTOH, with both firewalls off, machine B can open up the workgroup and see
machine A.... although when it tries to open A, it throws "\\Asus is not
accessible.... You may not have permission.... The network path was not found."
in spite of A's having things in it's "Shared Documents" folder.

OTOOH, the goofey thing where A opens B's SharedDocs and sees itself persists...

Pete, I experience exaclty the same problem and I am loosing my hair
over this ! Have you solved this problem? May be we can help each
other ...
Here is what I know so far:
- Not a firewall issue: I have disabled firewalls on both A and B
- Not a network issue : I changed the cabling, isolated A and B on
their own network and still I experienced this problem
Must be a service configuration issue. My next step is to reinstall
Windows but I will wait a little for feedback from you before I do.
