Steps to follow when some particular site is not opening

You are surfing the net, viewing sites, doing all your regular stuff. You stumble upon a site that is not opening . what to do ?? Or a particular site is not opening , which used to work fine sometime before .

I faced the same problem . Was not able to open www.wordpress.com from my lappy . After googling a lot , found some fixes to save your day :P .

Fix 1: Check your Windows HOSTS file - Make sure there’s no entry in the hosts file that maps the website’s address to localhost or an incorrect IP address like 127.0.0.1 – it is a possibility if you have imported some third-party hosts file.

cmd /k notepad c:\WINDOWS\system32\drivers\etc\hosts

Fix 2: Find Faults in the Pipeline – Paypal website may be up and running but it is possible that the real problem lies with a router that is between you and the computer hosting the Paypal website. Do a traceroute and check for messages like “Request Timed Out” – they will help you find the location of the breakdown.

Type the following command in the Run Window:

cmd /k tracert www.paypal.com – remember to replace Paypal with address of the website that is unreachable.

Fix 3: Clear DNS Cache – The DNS cache keeps a record of sites that you have recently visited on your computer. If that gets corrupted, you may have issues opening sites that were previously accessible without problems.

Type cmd /k ipconfig /displaydns in the Run window to see the cache entries. If that unreachable website is listed in the cache, type cmd /k ipconfig /flushdns to clear the cache.

Fix 4: Website May Be Blocked – The chances are rare but it is possible that access to some particular website may be have been restricted by the Office firewall. To test this, send an email to www@web2mail.com with the problematic website URL in the subject field. If the website is up, you will get a text copy of the web page in an email message.

Fix 5: Suspend the Anti-Virus and Firewall – If you are running an external software firewall or anti-virus program (like Norton, ZoneAlarm, etc), exit and restart the web browser. Is the problem solved now ?

When nothing works, open 192.168.1.1 and reboot the modem. If that fails, restart your computer and as a final step, call your ISP support.
