Delete a client lease

Applies To: Windows Server 2003, Windows Server 2003 R2, Windows Server 2003 with SP1, Windows Server 2003 with SP2

To delete a client lease

Open DHCP.
In the console tree, click Address Leases.

Where?
- DHCP/applicable DHCP server/applicable superscope (if used)/applicable scope/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 needed, give the client a new IP address. At the command prompt on the client computer, type ipconfig /renew.

Notes

To open DHCP, click Start, click Settings, click Control Panel, double-click Administrative Tools, and then double-click DHCP.
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.

Your server might function differently based on the version and edition of the operating system that is installed, your account permissions, and your menu settings. For more information, see Viewing Help on the Web.
