DHCP question

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?

Bad_Address's will eventualy expire. Set Conflict detection attempts to more than zero on Advanced tab of DHCP server (or IPv4 node) properties. This will prevent assignment of IP addresses which are still in use.

Also a power cycle of your switch may help, so you can trigger all machines to obtain new IPs via DHCP. So also machines will pull new IPs whose lease is due in hours or even days depending on how long it was set b4.
