Lost connection to Internet

[Jack]

Hello,
After turning on computer there is not connection to Internet, and
I do not know what else I can do to restore it.
1.
There is a connection to Internet in the Virtual PC guest (Windows XP).
Only host (also Windows XP) lost the connection.
2.
I restored host Windows XP to the earlier date and that did not help either.
3.
There is not response from Ping command I used in command window.
4.
Local Area Connection Status shows only increased number of bytes Sent but
the Received bytes do not change at all.
5.
In Network Connection window I clicked on 'Repair this connection' -->Local
Area Connection and that did not help either.
6.
I have 3 other computers connected to the same switch and all have
connection to the Internet.

What else should I try or check (besides reinstalling Windows) ?

Your comments appreciated,
Jack

What antivirus/security programs are installed on the host OS?

NOD32

NOD32
Thanks,

No third-party firewall such as Zone Alarm? If yes, then there was a known
issue with ZA connectivity. Get the latest update or uninstall it and use
the built-in Windows Firewall. If you are just using the WF now, try
updating the network adapter drivers. Get them from either the mftr.'s
website (third-party NIC), the motherboard mftr.'s website if onboard, or
the OEM's website for your specific model computer if you have that kind of
machine (Dell, HP, etc.).

You know the NIC works because the vm can get online so replacing it isn't
the issue. Of course, the vm isn't using the same drivers as the host.

No, just WF but I disabled it.
If it is a card, then why restoring to earlier date does to help?
It should restore driver to previous condition, I assume.

I wouldn't make that assumption. I'd update/reinstall the NIC drivers just
to make sure because that wouldn't hurt and it would help narrow down the
troubleshooting.

Otherwise, see if the host can get on line using Safe Mode With Networking.
If it can, then you know something you have running in the background is
the culprit. In that case, clean-boot troubleshooting is useful.

No, it is not a driver. I have uninstalled it and made a new install again
(after reboot).
I have noticed another thing, though.
In Network Connections window I do not have listed Internet Connection icon
nor Internet Gateway headline as I do have in my VPC guest and other
computers on network.
When I use 'Create a new connection' wizard it ends without any error, but
the new connection is not made!!!!

It's very difficult to troubleshoot connectivity issues like this without
being able to see the computer. I don't have any more ideas for you.
Something must have changed between the time things worked and the time
they didn't but I have no way of knowing what that would be.

I'm sorry I was unable to help you.
