The Ultimate Guide to Changing Your DNS Server

Try cleaning your browser's cache.
Make sure your DNS server is working correctly. You can try switching to openDNS and see if that helps. Also, Google has an open DNS option.

1. Click Start and then Control Panel
2. Click View network status and tasks
3. Click Change adapter settings on the left portion of the Window.
4. Double-click the icon for the Internet connection you're using. Often this will be labeled "Local Area Connection" or the name of your ISP. If you have multiple connections, make sure not to click the one with the red X.
5. Click the Properties button.
6. Click and highlight Internet Protocol Version 4 (TCP/IPv4) and click Properties.
7. If not already selected, select Use the following DNS server addresses
8. Enter the new DNS addresses and then click Ok and close out of all other windows.

openDNS:
DNS1: 208.67.222.222
DNS1: 208.67.222.222
Google's DNS
DNS1: 8.8.8.8
DNS2: 8.8.4.4
Hope this helps.

problem with your internet setting

Check to see if you have an add-on in your browser that blocks the website (or try an alternate browser). Check your hosts file (depends on the OS as to its location). Try using an alternative DNS namserver (see Google DNS). If these fail, ask your ISP if you are being blocked.

so what's the problem? Can't get to any websites? do you have a static ip and static dns or are they dynamically assigned? You may even have a bogus proxy set in your browser. Pull up a command prompt and try to ping www.google.com. If you can ping google, then dns is working fine.

Let me know what happens. Also, if you want some help, ask a question with details, don't just say 'dns error' as this is not enough information to figure out what is happening.Help us to help you.

You should contact your PROVIDERS access. Ask the IP address of DNS server, and put in the web configuration (TP / IP) of your network connection ..
That's it.

1.1st try to do a virus scan first in your computer 2. if no Virus found call your internet provider and have them do a tracert test. 3 they might give you a different dns number to rectify this problem

Hello :

Please try this solution here :

- VPN
A VPN lets you access Facebook from a normal internet connection. It’s a little bit of software that you install on your computer and then run after you connect to the internet. It sends all of your internet information through a different computer (located in the US or UK for example)… Try www.witopia.net for more information!
- Proxy
A less elegant option, but just as useful, is to use a web based proxy. There are many of these available, one of the best is ’sneak me’ (www.sneakme.net). You input the web address that you want to access and then click on ‘OK’ and you can go straight to the site you need.
- Business firewall bandwidth
Some businesses buy bandwidth directly from Chinese telecommunications companies, so multinationals for example can have full access to the Internet without any interruption.

You will need to get the internet connection settings from your service provider. Contact your mobile service provider and download the settings. Also some service providers require you to activate some kind of internet packs before browsing. Check if this is the case with your SP too.

When the DNS fails, it is a problem on your internet service provider's end. You should try to see if you can still access the internet, if not than contact your ISP.
