DHCP Renew for all network computers
How do I force an immediate IP release and renew of all DHCP clients on my domain controller?
How do I do this for just one client?
Where do I change the settings for how often client computers do this automatically? Is it a group policy thing?

So, I can't force a individual client to immediate release and renew the DCHP settings from the server?
How do I change the lease time on the dhcp server?

Hello,
But you can change when the lease is up on the Dhcp configuration so the clients will have to renew their leases for the IP address.

Connect to your DHCP server and check the Scopes Lease Duration? (under Scope Properties)
By default, the renewal will occur at Half of the Lease Duration (8 day lease will renew on the 4th day). If you want this to be sooner you can change the Lease Duration to something short. (typically wireless would be short - 4 hours, LAN would be longer 3 - 8 days depending on your clients needs)
Run ipconfig /all and you will see the Lease Obtained and Lease Expires information.

the time for the lease to be valid is configured on the dhcp server.
you can run the commands
ipconfig /release
ipconfig /renew
I think You cant run it for all machines from the AD controller.
