no dns name

I have a problem with Xp pro, been happening since my ISP switched to ADSL
modems, I lose the DNS name within my lan connection, I can talk to the
modem, and that is it. it has worked fine all last week with no problems, I
came home from work last night no internet, and this morning still no joy, my
ISP can talk to the modem, I can't ping anything using the Cmd Screen. I've
tried flushing the ipconfig and renewing, no joy. my ISP is also puzzled,
they are esculating it, has anybody some ideas? i use ie6 and Firefox,
neither works, no other routers are between my pc and modem and yes the ADSL
can act as a firewall, but that's disabled, so is KIS Kaspersky internet
security in fact i uninstalled it just as a test, no change.
This has been an ongoing problem, I'm sure it's my ISP they are just as
sure, it's not. I'm getting fed up. with the on/off access to the internet.

I had an ADSL modem that suffered from the same problem: It would not
resolve names by itself. I fixed the problem by asking my ISP to give me the
IP address of his DNS server, then manually setting the DNS address of each
PC to this value.

Can you ping an external IP address, e.g. 72.14.221.104 (Google)?

I did that also, set each pc to a static IP address supplied by them, no dice.
and no I can't ping any external ip address, all I get is a time out.
I think there is a problem with the modem, I may exchange it for a different
one.

Try this software download from a working machine:

I'm using my work pc, so no downloads possible, I'll have to find a friends
pc or something else.

If you cannot ping an external IP address then this is not a DNS issue. It
could be one of the following:
- Firewall setting
- Incorrect Default Gateway address
- Defective modem
- Defective network adapter
- Bad CAT5 cable
The issue is usually resolved by trying with a spare of each of the above.

That program won't help, if you can't ping external IP addresses.. I
missed that detail. Sorry

Here's the latest, I regained internet connection unknown as to what if
anything changed, but when I do ipconfig the dns name is blank, is this
expected? I would have thought I'd have something in there, not just blank.

Normally the Gateway and Primary DNS server assignments point to
your Broadband Access point.

Not specifically to address your issue, but you can use a free service
called OpenDNS that provides alternate/possibly better service Domain
Name System than your ISP offers.
Info and instructions at OpenDNS website: http://www.opendns.com/
The OpenDNS servers are:
208.67.222.222
208.67.220.220

well IP numbers wise, it points to my ISP, it's just the DNS name itself is
blank, I find this confusing, as it's blank when it works, and blank when
it's not working, so could this be a problem within windows, as it appears to
be sporadic, works for a week or so, then goes belly up for a day or so, then
it works, regular DSL didn't do this.
just the ADSL

As you can see, that setting has nothing to do with your problem. DNS name
can be empty. You only need primary/secondary DNS IP addresses so your PC
can resolve domain names.
so could this be a problem within windows,

I seriously doubt your problem is in the computer.

It sounds more like ADSL problem. I've been having a similar issue since
January. ADSL becomes extremely slow at random time. Sometimes it becomes so
slow (slower than 100Kbps) that I can't use it any longer. The speed goes
back to normal (1.2Mbps downstream) if I leave it alone for about 1 hour.
Problem comes back in less than 1 hour. Very frustrating.

The past few weeks has been ok. The speed goes back up to 1.2Mbps (I got
1.5Mbps connection). No changes have been done on the ADSL or my PCs.
regular DSL didn't do this. just the ADSL

Care to explain what "regular DSL" mean? Where do you have "regular DSL"
installed?

ADSL stands for Asymmetrical Digital Subscriber Link.

Basically it means the upload and download speeds are different.
Since the majority of data is download it's speed is much higher
than the upload speed.

Many providers now offer Symmetrical DSL but it's usually found
in Business class services.
