DHCP Interoperability
Applies To: Windows Server 2008
If you plan to integrate DHCP with other technologies on your network, be sure to read the topics in this section.
DNS servers provide name resolution for network resources, allowing DHCP servers and DHCP clients to register with DNS. For proper authorization and operation, the DHCP server relies on a valid AD DS configuration. The DHCP server must find a valid directory services-enabled domain controller. For more information, see DHCP Interoperability with DNS and DHCP Interoperability with AD DS.
You can use the DHCP Relay Agent with Routing and Remote Access to give scope options to dial-up clients or to virtual private network (VPN) clients. The dial-up or the VPN client will continue to receive an IP address from the Routing and Remote Access server, but it might use DHCPInform packets to obtain additional WINS and DNS addresses, a DNS domain name, or other DHCP options. The purpose of DHCPInform messages is to obtain DHCP scope option information without getting an IP address. For more information, see DHCP Interoperability with Routing and Remote Access.
Using NAP, DHCP servers and Network Policy Server (NPS) can enforce health policy when a computer attempts to lease or renew an Internet Protocol version 4 (IPv4) address. However, if client computers are configured with a static IP address or are otherwise configured to circumvent the use of DHCP, this enforcement method is not effective. For more information, see DHCP Interoperability with NAP.
