Re: Block Unauthorized Computer



Hi Dave,
You have to use some form of network access control. There's different ways
to do this:
- MAC address restrictions on the switch
- some form of authentication or validation, e.g Cisco NAC. Also WS2008 has
features for this,

My servers are Server 2003, SP2. I have DHCP running well. I noticed a
computer name in the Address list of the DHCP server that is not a
computer that belongs to our company. All I have is the computer name and
MAC address, which DHCP catches.

How can I block or prohibit this computer from getting an IP address or
from using our network for whatever purpose??
