I have a WAN setup (vpn tunnels), windows 2003 standard server, all xp pro clients, all computers on active directory, 1 dhcp server (also functioning as dns) giving out IP's, c class.
I want to restrict access to any computer that is not part of the domain (logged in with a username and password - so joined to the domain).
How do I prevent the DHCP server from assigning non-domain computers an IP address? what hardware and/or software do i need? How does the configuration look like?
If I have a visitor that needs to pluggin to the network, but I don't want to join his/her personal laptop to domain in order to gain access to Internet/email only - what is the workaround there?
