Are any APIs for Win NT 4.0 that can be used by an application to trigger DHCP client operation on specified network interface ? I know there are DHCP client APIs (or DHCP options) but i guess they r primarily for requesting DHCP options from the server. Can they be used somehow to request an address (along with standard options) ? Also IP helper SDK only has IpReleaseAddress & IpRenewAddress APIs but no APIs to initiate DHCP client process. Am i missing anything ?
