Some popular sites that are often blocked in offices, school or workplaces are YouTube, MySpace, Messengers, last.fm, Pandora, Bebo, Google News, Typepad, Orkut, ebay, Blogger blogs, Photobucket, AOL AIM, Facebook, Flickr, etc. etc..
However, there are some methods to bypass internet filters and corporate firewalls to get you unblock and access to restricted websites banned at some universities or office.
First you can go to “program start>run”.
Then type in “cmd”, after that a command prompt will be shown.

I should type “ping www.youtube.com” as above.
Next thing to do is to press this enter key on your keyboard.
