SYMPTOMS

When viewing the lease expiration of all Dynamic Host Configuration Protocol (DHCP) reserved clients for a scope in DHCP Manager, selecting "Scope, Active Leases, Properties" indicates that the "Lease Expires: Infinite". This is only true if the scope is created with an unlimited lease duration. If the scope's lease duration is limited to a specific period of time, the lease expiration for the reserved clients will match the expiration of all addresses in the scope.

CAUSE

The lease term of a DHCP reserved client is determined by the lease duration of the scope in which the reservation is added.

RESOLUTION

To create reserved clients with unlimited lease durations, create a scope with an unlimited lease duration and add reservations to that scope.

STATUS

Microsoft has confirmed this to be a problem in Windows NT versions 3.5 and 3.51. We are researching this problem and will post new information here in the Microsoft Knowledge Base as it becomes available.
