Lease Delete Data For Free

It isn't possible to change the DHCP lease time in your device's network settings as this is controlled by the DHCP server that allocates IP addresses, which is usually your network router. You'll need to have administrative access to your router to change this.

Start the Microsoft Management Console (MMC) DHCP snap-in (Start, Programs, Administrative Tools, DHCP). Select the Scope that contains the leases to be deleted. Select the Address Leases container. Right-click the lease to be deleted and select Delete. Click OK to the confirmation.

From the Data Management tab, select the DHCP tab -> Leases tab -> Current Leases. Click the check boxes beside the IP addresses of the leases you want to clear, and then click the Clear Lease icon.

A DHCP lease is a temporary assignment of an IP address to a device on the network. When using DHCP to manage a pool of IP addresses, each client served on the network is only renting its IP address. Thus, IP addresses managed by a DHCP server are only assigned for a limited period of time.

Deleting the lease will cause other machines to be able to get that IP. What you want is either to run ipconfig /renew via psexec or to script the renew in PowerShell and run it remotely. Alternatively, if the users reboot they should get the new configuration options.

In the Command Prompt, type ipconfig /release and press Enter.

To clear an active lease: From the Data Management tab, select the DHCP tab -> Leases tab -> Current Leases. Click the check boxes beside the IP addresses of the leases you want to clear, and then click the Clear Lease icon.
