PCs no longer able to network

[Guest]

My wife and I have 2 PCs on a small home office network. Both PCs are
connected to hub and directly to the internet. I don't know what I've done,
but my PC on Windows XP can no longer connect to her PC on Windows 98. The 2
computers were networked fine until last week. I have re-run the network
setup wizard on the XP machine and run the setup disk on the 98 machine
already, and have looked around all sorts of tools and can't find anything
else wrong. Both computers are still able to connect to the internet and get
email, but neither can ping the other. This is frustrating because we have
one printer and both need it. I have also checked that the XP firewall is
turned off.

When you say "Both PCs are connected to hub and directly to the internet." do
you mean both PCs have their own Internet connection, through a separate
modem, or ADSL connection, if so type winipcfg, from a command prompt on the
98 machine, and ipconfig/all on the xp machine, compare the results and check
that they're on the same subnet.

If you truly have a hub instead of a router, that's the most likely cause of
your problem. Both PCs are getting IP addresses from your ISP and most
likely one of them has changed, and the new address is in a different range
than the old address.

Get a router to replace your hub. It will make networking easier and will
provide a layer of protection between your PCs and the Internet - currently,
if you're using a hub, there is no protection and both PCs are being
directly exposed to any passing hacker, cracker or bad guy.

Both PCs are connected to a hub and a single modem. There is a firewall
between the hub and the modem though.

It's this linksys 5 port switch. The PCs have been networked with this
hardware before and I haven't had a problem until last week. As for a
firewall, I have one installed between the modem and the hub. Both PCs are,
therefore, also behind the firewall.

Again, as I mentioned earlier, if you don't have a router between you and
the Internet, your computers are getting "random" Internet IP addresses. A
router will assign both computers an address in the same range and make
networking possible again.

Then how did it work before? This isn't something that hasn't already been
done. It's somehow been undone.

More likely than not, the PCs just happened to get addresses in the same
range previously and now they're not.
