"Lost" DNS on WIndows XP Home

[Bob]

My Windows XP Home Edition has been running fine for a long time. But
suddenly when I booted up the computer this morning, it failed to connect to
the internet. I have other computers on the network and internet was fine.

From this Windows XP system, I can still remotely connect to other systems
on the local area network via their IP addresses 192.168.xx.xx. But when I
tried to hit websites such as http://hotmail.com in internet explorer 6, it
would not load.

It's as if I've lost my DNS service. I checked ipconfig/all and it reported
everything normally. I even did an ipconfig/release and ipconfig/renew,
that did not help. The Windows Firewall set up normally also.

Can someone tell me how I can re-engage my internet connection on this
Windows XP?

Thank you.

If you are the admin for your NAT router, check if you can connect to its
web server used for its configuration. That connect is usually is via an IP
address for the LAN-side of the router. If you can't connect then try one
of the other working hosts. Using ipconfig /all and looking at the DCHP
table in the router (whose DHCP server is presumably being used to assign
intranetwork IP addresses), check that the one used by your troublesome host
doesn't duplicate one assigned to a different host.

Presumably you are using DHCP assigned IP addresses rather than static IP
addresses. If you are using static IP addresses then you need to make sure
the subnet that you assigned to the host is in the same subnet as the
LAN-side IP address of the router (many don't allow cross-subnet connects on
the same LAN-side interface). So if your router's DHCP server is at
192.168.1.11 and its DHCP server assigns IP addresses in the range of
192.168.1.100-192.168.1.150 then your static IP address should be something
like 192.168.1.x (where x is, say, 200 so it is outside the range assigned
by the DHCP server).

Presumably you haven't blocked that particular host from connecting to the
router or to its WAN-side interface to make the Internet connection. Enable
logging in the router. Try to make a connect to a web site using its IP
address and check the router's log to see that your connect was successful.
Then repeat but use the IP name and check the router's log.

I would think that you have already tried disabling the software firewall
rather than just assuming it works. You never mentioned WHICH router you
use but then you didn't even bother to mention your network setup. Maybe
you're using ICS on a gateway host. Whether a router or ICS, your TCP/IP
connectoid needs to specify the router or ICS host as the gateway because it
is that host which provides the interface between your intranetwork and the
Internet.

Shut down, and wait a minute. Restart. See if it works.
