Hi, I am very new here, so I am not sure if it is the right place for my problem, but I will risk. I've already asked for help in a different section, but no one was able to answer my questions.
I am trying to connect to Internet using Tiscali Broadband,it says it's connected, the modem has two steady lights,but I am getting the DNS error when I am trying to open any websites in my browser (Internet Explorer 6.0) or when I am logging into MSN Live Messenger it reports that I am facing a DNS problem on my PC. I've pinged my IP address and my DNS servers, I asked my collegue to ping my IP and DNS externaly and it was successfull. I am unable to access any websites even using their IP addressess.
I've reinstalled the Tiscali Modem and rebooted the PC couple times. I am running out of ideas what could cause this problem. All my settings seem to be fine as it worked allright on Tuesday morning and I haven't changed anything. I also run a scan on the PC to check if there's any spyware but it didn't find anything.
I don't have any personal firewalls installed and the Windows firewall is currently turned off.
I would really appreciate your help as I am very very :sad: :sad: concerned.

Try this out then:
1. Click Start then Run and type in cmd then press Enter...this will bring up command prompt.
2. in command prompt type ipconfig /flushdns (you will get a message saying successfully flushed DNS)
3. type exit and try browsing again

If this does not work than do the following:
If this is Windows XP with SP2 then do the following:
1. Click on Start then run again and cmd should still be there press enter.
2. Type in (no quotes) "netsh winsock reset catalog" then press enter(in a few seconds you should get a message saying that system must be restarted)
3. Type exit then enter.
4. Click on Start then Turn Off Computer then click on restart then when system comes back up try browsing again.

If this is not a computer with SP2 let me know and I will post the instructions for Sp1.

Hello,

I am having the same difficulty. I am using Windows XP service pack 2, and I'm connecting through a Broadcom 440x 10/100 Integrated Controller.

I tried the above steps, and completed them successfully. However the problem was not fixed. I would appreciate any other suggestions though.

Thanks in advance.

I sure hope someone has an answer for this one. I've been pulling my hair out for 3 days now. I'm a software developer, and am somewhat familiar with networking and OS guts, but can't figure this one out:

We have 8 Windows machines on our LAN and all work perfectly except ONE, which uses XP Media Center (Home) SP3, and worked fine until last week.
I can ping everywhere, using both IP address & machine/domain name.
I can map drives.
I can access this machine from other machines using Remote Desktop.
But IE7 is dead, just displays "IE cannot display the webpage".
Network diagnostics results are attached.
Windows Firewall is OFF. No other firewall installed.
Tried "netsh int ip reset c:\resetlog.txt", Tried "netsh winsock reset catalog", Tried "ipconfig /flushdns", Tried installing IE8.
DHCP looks OK, no IP conflicts, etc.
Time to get the hammer?

I just ran into this problem as well and the fix was to go into IE, Tools menu, Internet Options, Connections tab, click the LAN Settings button and uncheck the Proxy Server box.

Hi there,
I tried your suggestions, but I get the message:

What should I do? The IExplorer runs OK, but the mozila is not working.

Thanks

The problem that I had was with the settings of the AntiVirus that I was using. Somehow it was set so that it would block Mozila.
You can check that as well.

If you don't have any, you can check also the Vista Firewall.

I'm using Windows 7 Home Premium

I'm having an issue with my computer. I have a wireless connection & it says it's connected, but when I click on IE it will come up a blank page. When I go to the tools section on the browser I can't click on internet options.

Do you have any other browsers like firefox or chrome? If so, do they work?

Open a command box (click on start button, type cmd in the search box and press enter) then type ping www.google.com what result do you get?

If you are on a 'company machine' this might be the reason you are seeing this, Where are you trying this from. if at Home then you need to provide a little more info.
