How can i unblocked facebook blocked by our administrator?

Probably blocked by the administrator for good reasons like your there to learn not to fritter away hours on facebook.

This means that your internet/network administrator has blocked the site. You can only talk to him/her to unblock it or go to another provider where it is not blocked.
Some people can unblock it, but it could be illegal and may lead you to problems.

Unfortunately, if it's being blocked by your network administrator, you'll probably have to get them to unblock it. It's really going to depend on what's doing the blocking.

Dear hassan27:

You cannot login the facebook account if your computer has been blocked. You can contact your network administrator to unblocked your facebook account. It happen to me sometime. I just click the network administrator on the blocked facebook website and fill up the requirements and follow the instructions and send. They will email it to you. Just try it.

Inform me if you have made it.

Regards,

Hi Friend, As you have mentioned that the laptop is a school laptop, it might be possible that the school administrator has blocked that website. Unfortunately, without the administrator permission you can not access the facebook from the school laptop.

If it is blocked, there isn't much that an end user can do to unblock it.
Sorry.

I am assuming that you are accessing facebook in your office because if its at home, then you can control your router and unblock facebook. Most social networking site are blocked by your network administrator. If you believed that Facebook should be allowed in your office, talk to your network administrator and ask him/her to unblock facebook.

You will have to contact the network administrator at your school and ask them to unblock for a short period of time. You may also need to gather the student body and petition the principal to unblock facebook.

It must have been block from the school's server, so it's not possible to unblock it without consulting the System Administrator of your school. If you have the guts, try with the system administrator and try your luck. Good luck
