SUMMARY
=======

When a DHCP client IP address lease expires, the lease is retained in the DHCP
server database for approximately one day after the expiration.

MORE INFORMATION
================

This grace period protects a client's lease if the client is in a time zone
different from the DHCP server and the two computers' clocks are not
synchronized. The grace period also allows for the situation where the client
computer was not on the network at the time the lease expired.

The expired leases are included in the aggregate Active/Excluded count and in the
list of active clients in the Active Leases dialog box. They are distinguished
by a dimmed icon.

Additional query words: tcp/ip tcp dhcp
