DHCP Option : Release DHCP Lease on Shutdown (1) doesn't work

Discussion in 'Windows Networking' started by Antoine Golio, Nov 29, 2005.

  1. on a w2K3 SP1 Server , I have enabled the Microsoft Option : Release DHCP
    Lease on Shutdown (value 1) but the dhcp clients (W2K + XP) don't release
    their IP address when they properly shutdown (No event 12 in the DHCP log
    and nothing happens in the perfmon-dhcp-release/s counter).

    Any idea?

    Thanks

    shootg off the hip, but I am pretty sure that the release option is a client
    configuration. It has no effect on the server.

    Basically used so that the client starts with an IP of 0.0.0.0 and does a
    full 4 packet lease instead of a simple renewal and possibly creating a
    momentary ip conflict with a system that has since picked its old lease up.

    If you want your IPs to be available quickly, then you need to shorten the
    lease time.
