K-Flakes # 2010-11 : How to deal with - Valid internet website not getting loaded - problem

Recently, I found out having issue with my internet surfing with following symptoms - on all the web browsers, IE, Mozilla, Chrome on windows XP SP3.

A. Some of the websites were not getting loaded, with following errors - 

"OOpppss! Link appeared broken."
"Hostname not found."
"Cannot display page."

The error page may be different from browser to browser, but basically they say same thing, that the browser is not able to connect to the website.

B. Sometime web page loads, but not completely, and it appears horrible.

C. The page loads after you click 2-3 times refresh button.

D. Main Page loads, but other pages of the website do not load.

Below is the steps, which you can try to overcome this issue. I am putting all the steps corresponding to Windows XP, and IE 8. But I am sure that you can easily find the similar settings in Vista and other browsers.

1. Clean up Internet Temp directory. In IE go to Tools->Internet Options->General Tab. Click on delete button on the history section.

2. Scan your system for Malwares/Adwares - these are like viruses, and sometime they prevent you to access some sites. Note that if you think that your licensed version of Anti-Virus already take cares of these threats, then your perception is wrong; because in my case Norton, AVG and Mcafee ; all three failed to display those threats. MalwareBytes AntiMalware was able to detect some and SuperAntiSpyware was more effective.

Just download them; they are freeware; from their websites. Just google "MalwareByte AntiMalware" and "SuperAntiSpyware " and you should be able to land on appropriate websites.

Install them and scan your system. Hope they will be able to kill all such threat, if exists.

Now, see if your system works as expected.

If not, check for the below. 
- Find out if you are able to reach to the website through IP address. e.g. if you are not able to reach www.google.com, then open the below page:

or
or

I hope, you will be able to access one of these. If not try "nslookup" in any of the search engine, and you will get a list of websites for nslookup.

You will find a textbox on these website, where you can submit the website, you are trying to access; but browser not loading. e.g. in this case, I will put www.google.com. Please note that you should put only the main website address, not like www.abc.com/index.html . Just put www.abc.com
The nslookup will return you the IP address of the website. e.g. for www.google.com, you may get 74.125.53.106.

Now, go to web browser and type http://74.125.53.106
You should be able to get www.google.com. If you are able to get the blocked website by its IP address, it means that your system is either caching the website in negative DNS cache, or it is not able to use correct DNS service.

Try following:

1. Go to command prompt, by Strat->Run; type "cmd" and press enter.
Type "ipconfig /flushdns" followed by "ipconfig /registerdns".



C:\Documents and Settings\S>ipconfig /flushdns

Windows IP Configuration

Successfully flushed the DNS Resolver Cache.

C:\Documents and Settings\S>ipconfig /registerdns

Windows IP Configuration

Registration of the DNS resource records for all adapters of this computer has been initiated. Any errors will be reported in the Event Viewer in 15 minutes..

Now, try again. If your problem is still unresolved, try following:

Go to start-> Settings -> Control Panel. Click on network connections. Right Click on your Local Area network connection and click on properties.

Click on Internet Protocol (TCP/IP) and lick on properties button.
Check the "Use DNS server" settings. Select the radio button "Use the following DNS server entries" and enter the following IP address:



 208.67.222.222 
 208.67.220.220


Those, who might be curious about, which IP address these are, I would like to tell that the IP addresses points to OpenDNS - resolver1.opendns.com. This is a DNS service provider organization. Please visit their website www.opendns.com for details. The above entry should work for across all the regions, so don't worry about that.


I hope, your problem should be taken care by some/all these steps.


Best of luck.
