If you use Google Chrome and you’re getting the “server DNS address could not be found” error message when you try to visit some websites, don’t worry!
Here are four methods to try that have solved this problem for other Chrome users. You may not need to try them all. Just work your way down the list until you find the one that fixes the problem.
The error occurs maybe because you have an outdated, incorrect or corrupt driver – or more than one – that’s blocking your internet access to certain sites.
To rule this possibility out, you should ensure all your drivers are correct, updated and in good health. You can do this either manually or automatically:
Manual driver update – You can update your drivers manually by going to the manufacturer’s website and searching for the most recent correct driver. Note that for some drivers, you may need to try both the manufacturer of your PC and also the manufacturer of the component itself. If you don’t have the time, patience or computer skills to update your drivers manually, you can, instead, do it automatically with Driver Easy.
Automatic driver update – Driver Easy will automatically recognize your system and find the correct drivers for all your computer’s cards and components. You don’t need to know exactly what system your computer is running or who all the manufacturers are, you don’t need to risk downloading and installing the wrong driver, and you don’t need to worry about making a mistake when installing. You can update your drivers automatically with either the FREE or the Pro version of Driver Easy. But with the Pro version it takes just 2 clicks (and you get full support and a 30-day money back guarantee):
1) Download and install Driver Easy.
2) Run Driver Easy and click Scan Now button. Driver Easy will then scan your computer and detect any problem drivers.
3) Click the Update button next to all flagged devices to automatically download and install the correct version of their drivers (you can do this with the FREE version).
Or click Update All to automatically download and install the correct version of all the drivers that are missing or out of date on your system (this requires the Pro version – you’ll be prompted to upgrade when you click Update All).
This is a simple fix. Just go to C:WindowsSystem32driversetc and delete all the files there. Then try accessing the internet again with Chrome.
If Chrome’s host cache is corrupt or too full, you may not be able to access any websites. This is a very common cause of the problem, and quite an easy one to fix:
1) Open Chrome and type chrome://net-internals/#dns in the address bar, press Enter on your keyboard, then click the Clear host cache button.
2) Check to see if the problem is resolved.
If your DNS server settings are configured incorrectly, you may not be able to access the internet. Follow steps below to set them correctly.
1) On your keyboard, press the Windows logo key and R at the same time to invoke a Run command.
2) Type control panel in the empty box and click OK to open the Control Panel.
3) View by Small icons then click Network and Sharing Center.
4) Click Change adapter settings.
5) Right-click on the connection icon (either Local Area Connection or Wireless Network Connection), then click Properties.
6) Click Internet Protocol Version 4 (TCP/IPv4) then click Properties.
7) In General tab, do one of the following, depending on whether ‘Obtain DNS server address automatically’ is already selected. Either:
a) If Obtain DNS server address automatically is NOT already selected, select it, then click OK.
b) If ‘Obtain DNS servers address automatically’ IS already selected, select Use the following DNS server address instead, then enter the following server address and click OK:
Preferred DNS server: 188.8.131.52
Alternate DNS server: 184.108.40.206
8) Check to see if the problem is resolved.
Windows automatically stores the IP addresses of the websites you visit, so they open faster the next time you visit them. But if this cache becomes outdated or corrupt, it can stop you from accessing the internet altogether. To see if this is what’s causing your problem, simply renew and flush the DNS:
1) Press Windows+R on your keyboard, to open the Run box.
2) Type cmd then press Ctrl+Shift+Enter to open an administrator Command Prompt. (Don’t just press Enter or click OK as that won’t open the command prompt in administrator mode.)
3) Type ipconfig /flushdns and press Enter on your keyboard.
4) Type ipconfig /renew and press Enter on your keyboard.
5) Type ipconfig /registerdns and press Enter on your keyboard.
6) Reboot your PC and see if the problem is resolved.
