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.
