My boss wants me to block all users from accessing Facebook. I am running a Windows 2008-R2 Standard Server which also is running DNS Server.
I want to block Facebook regardless of which browser is used to get to that site.
The client computers are a combination of Windows XP, Windows Vista, Windows 7 and Windows 8.
I have read various articles on experts-exchange on how Facebook can be blocked, but the one option (that is the cheapest) suggests using a DNS Server entry of "127.0.0.1 www.facebook.com
". This seems to be the easiest solution, but I don't know how to implement it.
Your help is greatly appreciated.
