Can ping in one direction only

[Douglas]

I have two Windows XP Pro machines networked via a
Linksys router. Machine A has a dynamic IP address;
Machine B has a fixed IP address.

When I first turn on machine A, I am able to ping machine
B by both computer name and IP address.

After a few minutes, I lose the ability for Machine A to
ping Machine B by name and can only ping by IP address.

At this point, Machine A can ping Machine B by IP address
only, but Machine B cannot ping machine A at all (request
times out).

Both machines are in the same workgroup, I have NetBios
over TCP/IP enabled on both machines, and Node Type on
both machines is None. Neither machine is running ICF
and both are on the same subnet.

Any ideas?

If you find a solution to this please forward it to me. I
have an XP machine that can ping all workstations and
servers but none can ping the XP machine.

Do you have the firewall on the XP machine enabled? It would block a
incoming ping but not one going out.

No, the internet connection firewall is disabled on both
machines.

 

[Douglas]

No firewalls enabled on either machine.
