I'm troubleshooting a certain issue with my DHCP configuration, and need my Windows machine to ask for a "fresh" IP address, so I can see which address DHCP server gives by default.
When I do
ipconfig /release followed by
ipconfig /renew, Windows "proposes" its old IP address to the DHCP server (just checked with Wireshark, initial "DHCP Discover" message has Option-50 (requested IP address) with Windows machine's old IP).
Tried disabling/enabling network adapter. Same behavior.
Question: How can I force Windows to just ask for a new IP address, without proposing its old IP address.
