Five days ago I got my new PC , ASUS A7N8X motherboard
with on board LAN, called "NVIIDIA nForce MCP Networking
Adaptor" in the device manager and connected it to my
existing LAN which has a laptop on WIN98 and desk top on
WIN95. They were all seeing each other. The new PC is
running WIN XP Home.

Three days ago, the WIN XP became invisible to the others
and the others invisible to it.

I have been thru the entire trouble shooting process,
reformatted the new PC HD and reinstalled WIN XP to no
avail.

The Local Area Connection icon in the system tray flashes
and all checks say the device is working properly. The
light on the hub is on, the light on the motherboard is
on. The other pCs talk to each other so there is nothing
wrong with the hardware outside the new PC.

The new pc gets no response from pinging the others and
they get nothing from the new PC.

I conclude that the on board Adaptor is faulty and am
about to return it to the store.

Any suggestions?
Does the flashing icon in the system tray mean all is well?
 
Surprise! Today I switched the machine on and My Network
Places showed the other PC and the LAN was working.
This is a mystery as I did nothing to the system except
browse thru Administrative Tools looking to Enable Guest
(which wasn't there cuz I am on XP Home).
 
Excellent. Some observations.

- reformatting and reinstallation of operating system rarely fixes
root-causes of problems (despite what vendor help desks say). Avoid
doing this unless for exceptional and compelling reasons. Someone
telling you to do it is normally not exceptional or compelling.

- symptoms suggest, as you suspect, flawed network card on the motherboard.

- you should by all means contact your vendor and ensure they are aware
that there is potentially a problem with your new machine and that you
may need a replacement.
