We have set up our 2008 server with DHCP, DNS, Active Directory and ICS. All of our computers work great and are assigned a IP from the DNS Server.
One strange problem is that our Internet Cafe customers cannot access facebook.
Every other site we use will work without a problem but NONE of our computers will resolve facebook.
My head techninian decided to try the physical IP address of facebook and it was passed on to me that the computers would in fact resolve the IP address but not the facebook.com address.
I have never seen anything like it. I was joking to them that I could block facebook the other day and now it has happened without me doing a thing!!
