All my Clients that are on DHCP obtain a lease that is set to expire after the standard 8days
If i delete my leases from the DHCP scope which are currently in use. Then disable that DHCP scope and unauthorise the server will the clients not look for a new ip address until either a reboot or the 8days has expired. So any computer left on even though the scope has changed does the client still keep it's address?
So what i am asking is does DHCP comunciate with it's clients if it changes and update. I predict the client just gets an IP and then forgets about it until a reboot or a ipconfig /renew etc.
I am planning on turning off my current DHCP server and going to a new DHCP server.
But want to ensure if a computer does not turn off overnight it wont have an ip address that technically could be given out again on the new DHCP server.
