LAN was working and now it doesn't

[Tony]

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.
