IP addresses become APIPA when DHCP failover server running Windows Server 2012 or Windows Server 2012 R2 is unavailable

Applies to: Windows Server 2012 R2 DatacenterWindows Server 2012 R2 EssentialsWindows Server 2012 R2 Foundation


Consider the following scenario:
  • Two Dynamic Host Configuration Protocol (DHCP) servers are configured for failover.
  • DHCP Network Access Protection (NAP) is configured on both DHCP servers.
  • A client computer obtains an IP address from DHCP server 1.
  • DHCP server 1 is unavailable, and DHCP server 2 detects that DHCP server 1 is unavailable.
  • The client computer sends a rebind request.
In this scenario, the client computer cannot obtain the IP address from DHCP server 2, and an Automatic Private IP Addressing (APIPA) address is assigned to the client computer.
