Centrally manage all your network IP addresses from a DHCP server using the Bootp protocol when you have network hosts that support Bootp but not DHCP (Dynamic Host Configuration Protocol). Since DHCP relies upon broadcast traffic for configuration, a DHCP relay agent must be enabled on each network subnet serviced by the DHCP server because the routers that forward traffic between subnets will block DHCP broadcast traffic by default. Configure a Windows Server 2008 computer as a DHCP relay agent on each network subnet serviced by a DHCP server that resides on a separate network.
- Windows Server 2008 computer connected to each network serviced by the Bootp server
- Credentials of an Administrator account on the Windows Server 2008 computer
- IP address of the network DHCP server obtained from the DHCP server administrator
Log in to a Windows Server 2008 computer on network subnet with the user name and password of an account that has Administrator permissions on the computer.
Click the “Start” button on the Windows Server 2008 computer taskbar, and click “Administrative Tools,” then click “Server Manager.” Click the “+” next to the “Roles” item and click to expand “Network Policy and Access Services,” then click “Routing and Remote Access.”
Click the name of the Windows Server 2008 computer in the left pane of the “Routing and Remote Access” window that appears. Click “IP Routing,” then right-click “General” and click “New Routing Protocol” in the menu that appears.
Click “DHCP Relay Agent” in the “Select Routing Protocol” window and click “OK.”
Right-click the “DHCP Relay Agent” item and click “Properties” in the menu that appears. Click the “General” tab and write the IP address of the network DHCP server into the “Server address” field, and click “Add,” then click “OK.”
Right-click the “DHCP Relay Agent” item and click “New Interface” in the menu that appears. Click on the network interface from the list displayed that is connected to the network and click “OK.”
Right-click the “DHCP Relay Agent” item and click “Properties” and then click the “General” tab. Tick the “Relay DHCP Packets” box if not already selected and click “OK” to save the setting.
Repeat the above procedure for each network subnet serviced by a DHCP server on another network.
