Check for general errors and return its value to the DWORD variable dwRetVal (for more extensive error checking). DWORD dwRetVal Д¬all the IpRenewAddress function, passing the IP_ADAPTER_INDEX_MAP variable Adapter as its parameter. It is important that the first lease is expired, else the client machine will make a DHCPREQUEST for its first address and dhcpd will grant it as it will still be a valid lease. Restore the client-machine's network connection. It is assumed that the variable returned by GetInterfaceInfo is called pInfo. Expire old lease from dhcpd via omshell(1) by altering it's ends time to sometime in the past (e.g. Declare a DWORD object dwRetVal (used for error checking) if this variable has not been declared. (For help with the GetInterfaceInfo function, see Managing Interfaces Using GetInterfaceInfo). Obtain a pointer to an IP_ADAPTER_INDEX_MAP structure using the GetInterfaceInfo function. The following procedure assumes that the functions are not used together however, if the functions are used together, skip step 1.

It is common to use these two functions together, calling the IpReleaseAddress function and then calling the IpRenewAddress function, passing the same structure as the parameter to both functions. When a host has previously obtained a DHCP lease and IpReleaseAddress is called before the IpRenewAddress function, the DHCP client first releases the IP address obtained and sends a DHCP client request for a response from any available DHCP server. This DHCP server may not available or the DHCP request may fail. When a DHCP client has previously obtained a DHCP lease and IpReleaseAddress is not called before the IpRenewAddress function, the DHCP client request is sent to the DHCP server that issued the initial DHCP lease. It is common to use these two functions together, first releasing the lease with a call to IpReleaseAddress, and then renewing the lease with a call to the IpRenewAddress function. The IpRenewAddress function renews a lease on an IPv4 address previously obtained through DHCP. The IpReleaseAddress function releases an IPv4 address previously obtained through DHCP. The IpReleaseAddress and IpRenewAddress functions are used to release and renew the current Dynamic Host Configuration Protocol (DHCP) lease.
