I'm glad your PCs are talking and that you're seeing daylight again, in that
you solved your own problem (there's nothing like owning knowledge gained by
direct experience).
I also think, though, that you *may* just be "on the edge of the woods and
able to see daylight", but not actually out of the woods yet, and more
troubles down the road may plague you. Here's why:
You said you had already run the Network Setup Wizard *twice* before seeking
assistance (I'd wager dollars to donuts that BOTH times the Wizard finished
the message merely said that the Setup was completed; inferring no errors,
or, that ALL tasks to be done by the Wizard WERE *completed* SUCCESSFULLY)
Yet... Networking failed. Why? (At least...) because of the server service
not running (which you did mention in your 1st Post, and I purposefully chose
NOT to try and "surgically-techno-vise" you to repair just that and see what
happens; the why to that follows...)
Part of the Wizards job *IS* to configure and activate the server service.
It is a basic and obvious requirement. Yet, not only did it fail to do that,
it ALSO failed to tell you it didn't or couldn't. This, then, *trongly*
suggests that there was SOMETHING ELSE ALREADY wrong (or perhaps a better
viewpoint: not completely right) before you ever even RAN the Wizard, that
subtly interfered with its ability to properly do its job.
That takes you back a step (at least), to what I considered at the time the
most logical level that is dynamic and which all OS CDs are vulnerable to:
the software OS-interface to Hardware components directly envolved with the
faulty process, in this case the NIC drivers. That's why I suggested that you
start there, rather than going for the server service alone (inferring that
since the Wizard missed this the first two times, then you should refresh the
foundation that the Wizard works from _first_, then let it try again, because
it can configure ALL of the pieces properly in one swoop faster than we can
manually, provided all the RIGHT pieces are in place to start with).
Its like a Finishing Carpenter who builds the most beautiful kitchen
cabinetry in a house whose cement foundation is missing sand: eventually the
house will collapse over the faulty foundation and there goes the beautiful
cabinetry.
So, if the Wizard could "fail" at least once in this specific respect (yes,
it is a presumption that the failure is related to the driver, but certainly
a reasonable and likely one), what about others just as subtle? Without
researching and *knowing* the drivers' current-XP-compatibility, IMHO it is
foolish to presume otherwise. After all, a large quantity of drivers get
OS-dependant updates shortly after the OS (and therefore the cabfiles of CD
they came on) are released. Windows cabfile drivers are nice and convenient
for initial setup-and-go, but a REAL computer gets updated with newer ones as
they come out.
I also congratulate you for handling the firewall issue (something that is
commonly overlooked, admitedly I did so too in not mentioning it, not because
I don't know, just missed to remembering it). If you do decide to rebuild
your Network Stack and rerun the Wizard, then disabling the firewalls AND
disconnecting from your LAN (and the Internet) would be prudent while doing
so. Yes, the risk _is_ small, but why not ELIMINATE it? Unplugging a cable is
such a tiny task.
Granted, now your situation looks to be working as desired and may continue
to do so for an unknown period of time (after all it certainly is possible
that it *could* be completely corrected by now). But experience has clearly
demonstrated to me that "quick-fixes" rather than "correct-fixes" cause more
future headaches and downtime than it is worth to not do the job right in the
first place.
Best wishes and enjoyment in your new(ly-functional) LAN.
