I have got an internet connection but can;t open any websites. I just get the Error 105 err_name_not_resolved with a server problem. message

What is the OS. And when exactly you are receiving the error mesaage

Here are the simple steps to take.
error 105 Unable to resolve the server DNS address

Error 105 is one of the most commonly faced errors by a lot of users everyday who are using Google chrome
Error 105 is a DNS resolution error. - Which means when you enter the URL of the website and hit enter in Google chrome, it tries to resolve the IP address of the website using a protocol called DNS (Domain Name System). If chrome is unable to reach the DNS server, the name resolution fails and you get the error 105.
Solution:
Once you have verified from your internet service provider that there is no problem on their end, follow the step by step instructions below.
We are simply going to add a manual DNS address in Windows so that chrome is able to resolve DNS queries.
1) Press [Windows Key + R] to open the "RUN Dialog"
Alternatively, you can also click on the start menu, type run in the search bar, and you will have the RUN Program.
Once you have the RUN box, type in ncpa.cpl and click OK - This would work for all Windows operating systems including Windows Xp, Vista and 7.
2) Next, Choose the correct network adapter (from the icons)
If you are connecting to the internet using an Ethernet cable, then most likely you are using a desktop computer. Right-Click "Local Area Connection" and click "Properties"
If you are connecting to the internet using a Wi-Fi Connection, then Right-Click on "Wireless Network Connection" and click properties
3) After you open the properties window, select "Internet Protocol Version 4 (TCP/IPv4)" and click "Properties"
4) Usually you would be having both the options set to "Automatic"
In the section below, select the "Use the following DNS Server Addresses" and enter the following values Preferred DNS Server - 8.8.4.4
Alternate DNS Server - 8.8.8.8
and click "OK", then click "CLOSE"
You must now test your new configuration by browsing a website - you can also try and browse the website you were trying to get to when you got the error 105.

it seems that you have a problem connecting to the DNS server which is the server who knows how to resolve the internet address you enter into the IP.

did you change anything in your internet connection settings?
did you configure a router lately?

please do the follow:

1. Start --> Control Panel --> Network Connections
2. right click on your LAN and select properties
3. scroll down to the IP/TCP and select it
4. click properties
   
5. check the "Obtain and IP automatically
   

if this doesnt work you should contact your ISP

Go into the Tools area, select Options, then in the Privacy section, turn off DNS pre-fetching. Worked well for me.
