A failover relationship for Microsoft DHCP services involves configuring two DHCP servers to work together, providing redundancy for those DHCP servers. This helps to ensure that IP addresses are continuously available even if one server goes offline. The failover process involves two key modes:
- Hot standby: In this mode, one DHCP server acts as the primary (active) server, while the other acts as the standby (passive) server. The standby server takes over if the primary server fails.
- Load balancing: Both DHCP servers actively serve IP addresses, distributing the load between them. This mode is designed to optimize resource utilization and provide fault tolerance.
Note: To manage failover between two Microsoft servers, the DHCP
Agent must be running as a service account with sufficient privileges to manage the
DHCP service.
