Our desktop guys did a move on a certain subnet without telling anyone and now all the IP's in the DHCP range are full. The new machines on the subnet cannot get IP's. So I deleted all the IP's and lowered the lease times, so that all the machines would request new IP's. Now im getting some Bad_Address's in the scope. I set the lease times to 10 min. Is this correct? Should these addresses clear once the conflicted machines request new IP's?
