    Hi ALL, I need to configure a DHCP running on Cisco switch or MS2003
    with lease option of 30 minutes so that when the client starts lease
    renewal they will get a new ip address instead of keeping the old ip
    address. This needs to be done on the DHCP server side and not in the
    client side.

    All I've ever been able to do is change the pool such that the old
    addresses are no longer valid leases. In other words, say your current
    pool is 100-200. If you change it so that the new pool is 2-99, then
    when the client tries to renew the address is no longer valid, so it
    gets a different lease.

    I switched to ISC dhcpd because the Windows based ones don't seem to
    have nearly as many features, and the features that exist don't seem to
    work in a predictable fashion.
