I can't access any website through my PC

[marswoo]

I don't know if I have posted this in the right section. I'm a newbie web designer and I was so worried when after trying for several times, I can't access any website using my PC. There's internet connection because I was able to open Yahoo Messenger. But when I type a web address, firefox said "Not Authorized". Explorer also failed to open any website.

I'm so worried I might have clicked on something while toying around with the control panel. I am a designer and not a computer expert. I hope you guys can help me.

Thanks in advance.

I have moved this to the Storage & Networking forum. Hopefully you will get more exposure here.

As far as your problem, it sounds like a DNS issue to me. Are you using a router, or connected directly to the modem? Once we have established this, we can diagnose the problem further.

get a command prompt and then enter

nslookup www.google.com​

if you get a reply with an ip-address, then your browser is fouled,
otherwise, your dns is not reachable or its address is not proper for your
