I am setting up a new server for our small office.

Although I have only limited knowledge on network and server OS, follow along tutorial book does the job.

So far I have configured DNS and ADDS, but I would love to be able to block certain website access for the client computers.

I found the solution is through setting up another proxy server in the network, and make all traffic go through it only.

Can someone give me some idea on how to accomplish that?

I understand I need to assign static IP to the proxy machine, and the gateway and DNS will be configured as well.

How do I force all clients to use the proxy only? Is it through firewall?

If so, does that mean I need to manually configure that on each of the client computers?

Any help would be greatly appreciated  :D

If you have a budget buy a hardware firewall, then configure the blocking of website on the firewall.

Just call some vendor ask them if they can provide a demo and throw all the questions to the vendor you have in mind.

If you already have a hardware firewall, make sure you are subscribe to the service to block certain websites. Or check the manufacturer's forum of your firewall vendor, i'm sure they can provide you with some ideas.

About the proxy i'm not familiar wi
