    Again these five clients aren't releasing the ip, they are unable to
    renew
    it or receive acknowledgement of a leased ip.
    Something else on your network could be providing dhcp. A router that is

    dhcp enabled or a rogue dhcp server could be doing it.
    So, between yesterday and today you have had your dhcp server service
    stopped and you have rebooted 100 clients to test this theory?--And you
    have
    checked all 100 machines for alternate configurations?
    You might want to post in the windows networking group next.
