We have a Win2K3 server running AD, DNS, DHCP. The DHCP scope was changed from .100-.250 to a smaller scope, .100-.200 and our clients are still ending up stuck with .200+ addresses. Even when I release and renew the addresses, the revert back to the same old IPs. We want to install new equipment and put them on static IPs starting at .201 and up so this is a hindrance.
reboot the DHCP server
