In my office LAN I need to allow only the company's computers to access the Internet. We have ISA Server 2006 installed, regardless of not having managble switch which I could easily block ports to specific MAC Address (that's another war). The problem is that some workers bring their own PC's unplug the network cable from the company computer and plug on their own accessing the internet.
Is there any possibility of create some rule in ISA that only allows Internet access from specific MAC Addresses?
Thank in advance.
