Delete a Client Lease
Updated: October 16, 2008
Applies To: Windows Server 2008
You can use this procedure to delete a client lease.
Membership in the Domain Admins group, or equivalent, is the minimum required to complete this procedure.
-
Open DHCP.
-
In the console tree, click Address Leases.
-
In the details pane, click the IP address of the client you want to delete.
-
On the Action menu, click Delete.
-
Make a reservation with the IP address, or exclude it from the range.
-
Force the client with the existing lease to give it up. At the command prompt on the client computer, type ipconfig /release.
-
If required, give the client a new IP address. At the command prompt on the client computer, type ipconfig /renew.
If you want, you can cancel leases for all clients in the scope. To cancel all current leases, select all of the clients in Address Leases, right-click, and then click Delete.
Deleting a client lease does not prevent the server from offering that IP address again in a future client lease. It also does not prevent the client from requesting the address again, unless steps 5 to 7 are followed.
