Bypass local area network DNS with Windows 7

One of my friend told me about internet access restriction that he think little strange. He can’t browse popular browser like google, youtube etc but he can access local intranet web easily. He can use messenger and do ssh.

I ask him to test access the web with web based proxy like hidemyass etc but he can’t access that too.

He give me tcp/ip setting of his computer and after little change in dns he can access everything like usual.

The cause is simple : DNS

He use local dns that configured improperly that lead to above problem.

Quick solution for his case is change dns to others and I suggest him to use google public dns.

Here’s the steps :

1. Open Network and Sharing Center

Right click on internet connection icon.

2. Choose Change adapter settings

Right click on available connection.

Click Properties.

On Local Area Connection Properties click Internet Protocol Version 4 (TCP/IP V4)

3. Change DNS Server addresses

Let ip address as is and only change dns setting with google dns.

Save the setting by click OK.

4. Refresh dns cache with flushdns command

Everything set up successfully.

No more restriction and no more annoying internal web.
