Internet Connection Problem - DNS Error

I am having a problem with only one laptop that is a part of a network with several hundred computers. The machine was brought in out of the field and I don't know whether this is a new or existing problem. I re-installed the operating system and when I try to connect to the internet I get a DNS Error over the wired connection. I have used the same ethernet cable and port for other computers and they connect fine. I can actually sign onto my network and move around my network with no problems. I can map drives and do anything else I want. I have checked the IPCONFIG and it is getting the same information as all our other DHCP clients, so I know the DNS and configurations at that level are correct. Does anyone have ideas.

When you are plugged into a switch you get the DNS error, what about using wireless?  Also check the proxy settings on your browser.

Hi

Have you assigned a static DNS to the TCP/IP settings.  Try a good public DNS like OpenDNS.  It is a speedy public DNS.

208.67.222.222
208.67.220.220

Let's see what happens and we'll go from there.

Nothing changed. My IPCONFIG included them in there

Here is something else to consider. I am connected wirelessly to the internet and it is using the same DHCP server and setup as the wired connection

Open a CMD window and run

ping www.google.com

So wirelessly you're getting out, but wired you're not?  Check your NIC drivers.

Sorry it took me awhile to get back with you. Yes I am able to connect wirelessly. I checked the Dell website and downloaded the latest driver for the NIC and have applied it and I still get the same thing. I can to my network, map drives, etc but I still get a DNS error when I try and connect to the internet.

Disable your wireless connection and ping www.google.com with just the wired connection being used.

So wireless works and wired doesn't.  Are these on separate VLANs?

I can unplug the ethernet cable from the affected laptop and plug it into another laptop on the bench and it works great!

Titan22Commented:
Well that rules out the switch and DHCP server.  What's the network adapter?
0
Titan22Commented:
Check the Control Panel\Add Remove Programs for a network adapter energy savings program.  It's something that Dell installs to save energy, it's a pain.  If it's there delete it.

I checked the add/remove programs in the control panel and didn't find anything out of the ordinary. While I was there I uninstalled network controller software completely and reinstalled and still get the same symptom.

What is the network adapter?  Broadcom, Intel,....

Sounds like a firewall issue maybe, or do you have to setup a proxy?

What version driver is it?

The link above are the latest Broadcom drivers,  Find the network adapter that is yours install the drivers to see if that works.

Still no resolution. so is there any way I can clear some kind of cache. I am pulling straws for some kind of reason why it works ok on the local network, but not the internet

Run ipconfig /dnsflush from the CMD window.

Sorry ipconfig /flushdns

Take the laptop and connect it directly to the DSL modem there at the office or at your home. Let us know what happens. Your network settings, properties, for IP4; make sure they are set for DHCP , for IP address and DNS server address, these must be empty. Select Advanced and make sure that in IP Settings, the IP Address and Gateway are blank. The DNS tab, there are no entries in this area. WINS tab, WINS address is empty.

Disable your network adapter and re-enable it.  I'm running out of options.

I have done that numerous time .. I know what you mean about running out of options, but I do appreciate your inputs

Try looking at the local host file and making sure that no static DNS translation is configured on the host. The next thing is to actually do a "nslookup" command and query against the DNS server to see if you get a response. Let me know what happens.

It has to be the driver. Disable the network connection, delete the existing entry in Hardware and reboot.
Verify that the driver you are going to use is the correct one and reinstall.

I have done all that .. one of the last entries of Titan was a link for allthe latest drivers. Just got finished installing that and still no access to the internet. But weird think is that all my connections to my LAN work flawlessly ...

OOsorioCommented:
Go to \windows\system32\drivers\etc\hosts and remove any entries in the hosts file except for the local host entry
127.0.0.1       localhost

Long shot but who knows.

uucknaaaCommented:
OK .. Here's something to try!

I found an instance where the fix was to set your IP address, netmask, and gateway, manually.  It has something to do with the memory that is being used for the MAC address.   Try that and see if it works.

Set those three manually.  Ip address, netmask, and gateway.  

Let's see if it works.

I think he's already done static IP addressing.

uucknaaaCommented:
Hey ..

I mean he needs to do all three:  the IP address, gateway, and subnet mask.  Here is a link for you all to reference:

http://www.insanelymac.com/forum/lofiversion/index.php/t4987-150.html

I know this is in reference to another type of computer, but focus on the title and the network adapter.  They do reference a Dell computer down the discussion a ways.  Read  the stuff "Hater" wrote about the MAC address.

I just thought if we were grasping at straws that it might be something to checkout.

I know what you meant, he did all three.  

Skent:  What dell laptop is it?

Open Internet Explorer and go to Tools | Internet Options. Select the Connections Tab and make sure the there are no entries in the white rectangle. Further down select Lan Settings and make sure that the entries in this screen are the default settings. Other ports shouldn't be defined.

Another option is a limit of outgoing users (internet access) in the firewall. There are some firewalls that only allow a specific number of users going out to the internet. The computer behavior is that it works fine within the network but can't get out to the internet because the limit has been reached. To get arounf this you restart the firewall and as soon as it comes back up you go out to the internet on the problem computer.

what's your ipconfig /all output, mind posting it here?

nslookup was recommended, how did that go?
try resolving both internal and external addresses, for external try something totally random that you know you havent been to (however, seeing that it's a new install, and you havent been able to go on the web yet, it doesnt matter)

try different browser.

if you have live-on-cd OS kicking around somewhere (like knoppix) try booting from it, and go on the web. at least this way you would be able to eliminate HW failure.

All in all I have determined this to be a hardware issue. I have a green connect light on my NIC even though there is not any cable hooked into it at all. I tried to disable the internal NIC through the BIOS to see if that would have an affect on the link light.   IT didn't. I decided to go ahead and use an external NIC (PCMCIA) and it connects fine. I would like to thank everyone for their thought, but nothing worked.
