One system can't find Internet...?

[Kenneth]

Howdy,

Prior to a recent power outage, our five Win 2000 Pro
systems happily shared an Internet connection.

We use a cable modem, and pipe it through a router to the
systems.

After the outage, as is typical, we lost Internet on all
systems, and so went through the (now familiar) drill:

We powered down all the systems, powered down the cable
modem, and powered down the router.

We then powered up the cable modem, then the router, and
then each of the systems.

All but one of the systems now has Internet access.

That one system just can't seem to reconnect properly (to
the Internet, that is.)

That one system sees all the others on our lan, and all see
it properly. File sharing is fine both ways to and from that
system.

I have run IPCONFIG /release, then /renew and it is again
assigned the same IP address. I have re-booted the system. I
have un-plugged its network cable and re-plugged it to
another port on the router.

Still, no luck.

I would welcome any assistance on this.

Sincere thanks,

There could be a couple of different things going on, but I'm not gonna
confuse you. Lets start simple.

You should start by pinging a few different IP addresses. This will help
verify that your tcp/ip settings are correct and your network card is working
correctlty.


ping 127.0.0.1 (Local loopback test)
ping router internal IP address
ping other computer's ip address
ping external website IP address

note that some website do not allow pings so you wouldn't get a response.
Google and Yahoo are 2 sites that allow pings and you may want to use those:
Google: 64.233.161.104
Yahoo: 68.142.226.48

then you can try pinging all of the above by name to see whether you are
resolving names or not.

I have seen power outages do some weird things, but you say you can share
files with other computers, so it doesn't seem that your network card is
faulty or anything is corrupt.

What's the rest of the info? Is it pickingup all the settings correctly?
Have some services decided not to start on the one that cant access the net?
What happens if you ping an external domain? What happens if you then ping
that external domains IP?

Hi Adam & Barry,

It now appears most likely that I have been cursed with a
flaky cable modem.

I sincerely appreciate your suggestions.

All the best,
