Hi, all

Is DHCP FORCERENEW (RFC 3203 ) message supported in windows7/10?

I have a requirement where I need the DHCP server to initiate force renewal of client IP address.

Thanks.

    Hi,

    Thank you for posting in Q&A!

    Based on my research, the protocol implementation must implement DHCP-Authentication to support DHCP FORCERENEW message. However, DHCP-AUTH is not supported on Windows DHCP client and server. Hence it wont be possible for the Windows DHCP client to accept FORCERENEW messages.

    Instead, you can run "ipconfig/release" and "ipconfig/renew" on DHCP clients to renew IP addresses.

    For more details, please refer to:
