SYMPTOMS

Assume that a client computer requests a Dynamic Host Configuration Protocol (DHCP) lease from a Windows Server 2008 R2-based DHCP server. The DHCP lease that the client computer requests has a shorter duration than the lease duration that is defined on the DHCP server. In this situation, the client computer does not obtain an IP address from the DHCP server.

CAUSE

This issue occurs because the Windows Server 2008 R2-based DHCP server cannot handle a request for a lease that is shorter than the lease that is defined on the DHCP server.
