Hello all,

I have a problem with my laptop. After browsing the
internet for awhile (random amount of time). I notice
that my pc loses the ability to resolve urls. I can ping
ips all day, but if i put in a www. i get nothing. I
have loaded two different operating systems on this
machine and switched the NIC as well. The problem has
gotten better as of late (it can go for days without
losing resolution), but still persists. A reboot always
corrects the issue as well. I'm not running any special
firewall on the system either and my regular pc,
configured the same way, never has this problem.

The kicker is, the other day, I came across another
computer having the same problem, only much worse. After
a few pages, it too, loses the ability to surf.

Any ideas out there?

thanks,

dave..

What DNS addresses are you using? Can you provide an ipconfig /all of one of
the offending machine?

If you are asking what DNS servers I am using, the
answer is several. I have pointed to various DNS servers
with the same result.

Maybe one of the DNS servers you are pointing at is lame we can't see your
monitor and you won't even throw us a bone are we just supposed to make a
wild guess?

Ok..

I have multiple computers on the network. Only one has
this problem. All computers point to the same DNS
server. For troubleshooting purposes, I have pointed the
laptop to other dns servers, but the problem persists.
Also, I have recently come across another pc on an
entirely different network that is having the same
problem. The problem is not with the DNS servers, as no
other pc on either network has this issue. What I was
wondering is what could cause this.

thanks,

Ok, guessing mode...

Any errors in the Event viewer?
Any services (needed, but unknowingly) disabled? There are a few that are
needed for resolution to work.
Is it a firewall/proxy client?
SMS?
What OS is it?

Hmm,
Must be something top secret about his DNS server?
I bet he is using his ISP's DNS but he wants to beat around the bush about
it.

As I originally said...I have used several different DNS
servers...the problem is not with the DNS servers, the
problem is something on the machine. It is happening on
two different machines on two different networks. I was
wondering what could cause this.

In my original post I explained that the problem on the
laptop has held on to this problem through different OS
installs (with complete partition deletion and
recreation) and different network cards. I am thinking a
piece of hardware might be to blame, but since I changed
the card, I was hoping to get some ideas as to what to
look at. The other computers on the same network do not
have this problem, so the problem cannot have ANYTHING to
do with the dns servers.

I am not trying to be hard headed or secretive about
anything. I would just like someone to answer the
question.

dave..

The only thing I can suggest is to run nslookup against all your DNS servers
to see if they are answering. To get a verbose out put run
nslookup -d2

to change servers type
server <server ip address>

Try all dns servers you have listed in TCP/IP properties to make sure all
servers are operating and answering all requests. Since a reboot corrects
the problem I suspect a lame or not operational or mis-configured server.
You have to remember that Windows TCP/IP will only go through the list once
it will not start using a previous server in the list without a reboot.
If you have not done this, then you have not tried everything. If you are
convinced it is a hardware issue then you are posting in the wrong group.
I am not clarvioent and cannot see your monitor I will help you, but you
will not help me help you.

Try that test that Kevin mentioned.

If you don't want to give us any config info about this specific machine
that is having the problem or tell us if there are any errors in it's Event
logs, then it's guessing time and there are too many factors to guess.

And as I posted earlier with those questions about what your setup/config
is, I would, if I were you, double check and make sure the config on this
machine is the same as the ones without the problems.

Dave, it's really tough to help if you can't give us any configuration
information. Guessing just doesn't do us or you any good. If we guess one
thing, you may turn around and say, NO, It;'s not that! We'll guess
someothing else, and you may come back with the same answer. So if have
something concrete to go on, it will help narrow it down.

So far from the information you provided, it's as if we're just looking at a
menu in a restaurant without knowing the ingredients and the way it was
prepared and you're calorie pinching. So in that case, YOU'LL ask the waiter
a few questions to determine if you want the dish or not.

In the same manner, we need to know what your settings and errors are and
your config so we can help out.

See if you an answer those questions I previously posted. For your
convenience, here they are again with a couple others added.

Any errors in the Event viewer?
Any services (needed, but unknowingly) disabled? There are a few that are
needed for resolution to work.
Is it a firewall/proxy client?
SMS?
What OS is it?
Do you have AD running?
What DNS server IP addresses are you using?

Thanks Dave. Otherwise, it will be difficult to help.

If you can't provide it because of the information's sensitivity, I would
suggest to call Microsoft PSS (Product Support Services). The engineers
there will help you out. Matter of fact they monitor these newsgroups and
usually jump in with suggestions and collaborate with the MVPs to help out
you, the public. If you feel that the information is too sensitive to post
in the public forums, I would suggest to call them.

For your convenience, here's the MS PSS page to contact Microsoft and their
phone numbers, depending on what OS version what product you're having
problems with, etc:
http://support.microsoft.com/default.aspx?scid=fh;EN-US;CNTACTMS

Good luck.

Love to answer the question. But there are numerous factors that will cause
this.

Dave, at this point you haven't even told us what operating system is on
your laptop. If you need to reinstall TCP/IP if you feel that will help,
there are different procdedures for each OS.

<URL:http://homepages.tesco.net./~J.deBoynePollard/FGA/problem-report-standard-litany.html>

Tell us:

* The domain name portions of those URLs.
* The exact error messages presented by your web browser.

Then try manual "A" resource record lookups, with "dig" (or an
equivalent), on the same machine against those domain names;
and show us:

* The exact tests that you performed.
* The complete results of those tests.

It sounds to me like you are. What was your question?

Or is this a test?

Yep, I'm convinced its the hardware thow it away and get a new one.
That is about the best answer you are going to get on the information you've
given these guys.
Why are you wasting their time with this?
Everything they've tried to recommend you've thown out so why don't you just
get a new one.

AF> We're kind of like doctors....

The methods of problem diagnosis are the same in many walks of life, from
doctors treating patients to car mechanics fixing vehicle breakdowns. It's
amazing how many people think that problems with computers are somehow exempt
from the requirements for complete and accurate information that are there in
all other walks of life, and as a consequence present their computer problems
on free technical support forums in a way that would earn them very short
shrift indeed were they to do similar with a doctor or a mechanic whose time
and assistance they weren't paying for.

I suspect that only an exceptionally masochistic doctor would indulge the
following kind of timewasting for free:

Patient: Doctor, if I move one of my limbs for a while,
I encounter problems. Any ideas ?
Doctor: What sort of problems ? Which limb are you
moving ? How are you moving it ?
Patient: I said already. It's one of my limbs.
Doctor: It's tough to guess which limb. Please tell me.
Patient: It happens with the limb on the other side, too.
Doctor: But what are you doing, what actually happens, and
which part of your body is involved ? I'm a
doctor. I need a description of your symptoms to
work with and you aren't telling me a single thing.
Patient: I'm not trying to be hard headed or secretive.
I just want you to answer my question.

Just to add, I see you have a sbcglobal.net email address do you have either
of these DNS servers in your TCP/IP?
151.164.1.1 and/or 151.164.1.7

These are SBC's Authoritative DNS server they will NOT answer
non-authoritatively, they will only answer authoritatively.
They have recursion disabled on them, so if you are using them remove them
from anywhere in the network they are being used, these two servers cannot
be used as forwarders either.

WHen I tried it, with the d2 option, it said they were allowing recursion,

The first one is the send request the second is the answer, if recursion is
disabled it will not answer will recursion available.

Look at this this is the query for one of my public domains against SBC's
ns1.swbell.net which has recursion disabled, notice in the answer section
the recursion avail statement is missing. Instead of answering with what
would be normal output from a type A query it answers with a referal to the
