A. When a client is offered and accepts an IP address a 'lease' is created for x amount of days. To view current leases perform the following:

  1. Start the DHCP MMC snap-in (Start - Programs - Administrative Tools - DHCP)
  2. Expand the server
  3. Expand the scope whose leases you wish to view
  4. Select the 'Address Leases' branch and in the right hand window you will see the current lease details.

It will give details of the IP address, client name and the lease expiration date. Expired leases are also shown for approximately one day but have a dimmed icon. This grace period protects a client lease in the event of the client and server being in different time zones, clocks not synced or simply offline.
