DNS name cannot be read by win2k professional

[Guest]

My Laptop has windows 2000 professional (updated to Service Pack 2). I am
trying to install Verizon DSL. However, the connection to DSL activation
server cannot be established. The situation is:

1) My PC CAN ping server IP and get reply.
2) My PC CANNOT ping server url name (i.e. www.yahoo.com)
3) My IE browser CANNOT view any web page ("The page cannot be displayed.").
4) DSL technical guy told me that my PC is able to read DNS IP instead of
DNS name.

Is there any one can teach me how to do configuration so that my PC can read
both DNS IP and Name.

Thanks very much in advance.

Verizon's connection should assign your DNS server through
DHCP or PPPoE, and automatically allow you to resolve names.

If you have other network connections on your computer, check
them to make sure you haven't hard-coded a DNS server address
in one of them.

If you are connecting a router, you should subscribe with the software
from your local computer first to get registered, without the
router. Once that is working, you can configure your router to match,
and uninstall the software.

You should call Verizon back and ask for the next level of
support to help you.

There is no such thing as "DNS IP" -- DNS translates names
to IP addresses. IP addresses do not need further translation.

It is very clear from your post that DNS isn't working, which may
be a problem on your system, or something wrong with their
network, but either way they should be able to diagnose
the problem for you.

Steve,
Thank you for the helpful info. I have checked other network connections and
have no hard-coded DNS server address with them. I have no router, either.
I did some research and have a option to do.
In my local drive D:\WINNT\system32\drivers\etc folder, there is "host" file:
....
127.0.0.1 localhost
128.0.0.0 thiscomputer

Do I need add one more line at the bottom? such as
xx.xx.xx.xx DNS server name

This will let my PC match the DNS ip address with its name. Will this change
solve my problem? Thanks.

Larry:

I don't understand the 128.0.0.0 line. I'd take it out or
put a "#" in front of it to comment it out. Then
see if anything works better -- though I rather doubt it
will make a difference.

The DNS server you use is located by an IP addresss --
not a name -- assigned to provide DNS in your network
connection's TCP/IP properties.

A PPPoE or DHCP connection will assign the DNS
server automatically when it connects. A static
TCP/IP connection needs to have the DNS server configured
in manually. Putting in a hosts file entry won't help you.

If you open a CMD prompt you can type ipconfig /all.
That should show you what DNS server(s) are
currently assigned to perform lookups. If your PPPoE
connection is not active at the time, you should not see
any DNS server listed.

I should have mentioned this to you before -- there
are a number of malware/spyware programs that
hook in to the name service in your system and can
cause lookup failures. Especially if they are ripped
out carelessly.

I'd do a full malware scan with Spybot, and you might also
download and run one of the freeware "winsock" fixers
available on the Internet to make sure

Boom, you are genius. I download spyware seach and clean up spyware/adware in
my PC and finally got it works. I tried so hard for the past week and almost
gave it up. This is the good experience, though.

Thanks again.
