    That's not so simple because your DHCP clients get IP address lease from DHCP server and they do not drop this IP if you don't tell them to do that. But unfortunately this must be done on each client separately :(

    Even if you delete scope or DHCP database they still will be using issued IPs. Sorry

    Couldn't you delete the current assignments in DHCP and then also drop the network connection (network switch powered off), which would then force all clients to get new lease?

    Or is this too drastic for you?

    You can use free tools for that to discover used IPs in your network. I would suggest Look at LAN (but I think, it changed its name)

    or another IPsCanner angry
