Really i need some help here, currently am manging one of the branch in our company. I work as the Network admnistrator.
We use modems to provide internet to all pc through sharing it, but i found when all the pcs wher blocked, no access to Facebook or youtube.. I have tried to view the hosts file but nothing is indicated there, checking on browsers but still nothing, no software is installed for blocking, i thought may be they were blocked through the router, but we have no router here since we only use modems and switches.
I just need to know how they blocked facebook and youtube only that...
Thanks for any help provided...
