I know is frustrating when the DHCP server fails, all your network is down, been there. To start we need to create the Failover Cluster, and for that I have a guide right here. If you try to configure the DHCP service in the cluster right now you will get an ugly error:.

Network Infrastructure Servers. Sign in to vote. My reading of this feature is that DHCP leases etc. Is this a feature of R2? If so, can someone drop the link in the reply. In a load sharing mode deployment, which is the default mode of operation, the two servers simultaneously serve IP addresses and options to clients on a given subnet.
The client requests are load balanced and shared between the two servers. The load sharing mode of operation is best suited to deployments where both servers in a failover relationship are located at the same physical site. Both servers respond to DHCP client requests based on the load distribution ratio configured by the administrator. See the following examples. Two server computers and one client computer are used.
See the following figure. The failover relationship is always comprised of two DHCP servers. You can also configure DHCP failover on workgroup computers.
Time synchronization : For DHCP failover to function correctly, time must be kept synchronized between the two servers in a failover relationship. When the failover configuration wizard is run, it will compare the current time on the servers being configured for failover. If the time difference between the servers is greater than one minute, the failover setup process will halt with a critical error instructing the administrator to synchronize the time on the servers.
The following procedures are used to configure computers for the demonstration portion of the test lab:. These roles are installed on DHCP1 to mimic a domain environment.
DHCP failover can also be configured on a workgroup computer not demonstrated in this test lab. When prompted, enter a product key, accept license terms, configure clock, language, and regional settings, and provide a password for the local Administrator account. Click Start , type ncpa. The Network Connections control panel will open. The previous step demonstrates new functionality in Windows Server that enables you to search and run applications, settings, and files by clicking Start and then typing a search term.
Next to IP address type It is not necessary to provide an entry next to Default gateway. Click OK twice, and then close the Network Connections control panel. The Server Manager Dashboard is displayed by default. In the navigation pane, click Configure this local server. The System Properties dialog box will open. Wait for the installation process to complete, verify on the Installation progress page that Configuration required.
Click the Notification flag and then click Promote this server to a domain controller. See the following example. Click Next four times, verify that All prerequisite checks passed successfully is displayed, and then click Install.
