Two DHCP leases are created for each domain controller when you use the VDC cloning feature

Consider the following scenario:
  • You are using the virtualized domain controller (VDC) cloning feature that was introduced in Windows Server 2012. 
  • As part of your deployments, you implement Dynamic Host Configuration Protocol (DHCP). Therefore, cloned domain controllers automatically lease IP addresses when those domain controllers are created. 
  • Cloning finishes on each domain controller. 

In this scenario, you notice that two IP addresses are leased from the DHCP server for each cloned domain controller.

Note Only the more recent lease is used by the cloned domain controllers.
This issue occurs because the new server first takes a lease in its pre-cloned state during the cloning process. The new server then clones, becomes a new domain controller, and obtains a new lease. However, the old lease is not released during this process.
To resovle this issue, manually delete the unused address leases in DHCP, or let those leases expire as usual.

This behavior is expected.
