Restrict,Block facebook access at work,school pcs

Step 1 : Log into your Windows Account with Administrator privileges.

Step 2 : Access the Hosts File at C:/Windows/System32/drivers/etc/hosts

Step 3 : Add the following lines below the lines containing 127.0.0.1 localhosts as shown…

127.0.0.1 facebook.com
127.0.0.1 www.facebook.com

Step 4 : Save the File. You can add other websites like twitter, orkut etc. in the same way.

This should work fine. Facebook will be blocked in this case as long as the host file has the changes done above. 

The best thing about this way of blocking facebook and other sites is that if you change the host file of the main server PC in the LAN network then the whole network won’t be able to access the blocked website.
