I would think you need to get the client to restart to get it to go to your
dead end IP range. I would suggest once you take it out of the domain you do a
ipconfig /release on the client. I don't think working from the server side
only will work.

Subject: [NTSysADM] DHCP question
Date: Fri, 14 Mar 2014 22:37:11 +0000
I have a Windows 2008 server running DHCP. I’ll be kicking the remaining XP
systems off my network by the end of the month. I’m concerned that some of
them might wander back in and get reconnected. I’d like to set up DHCP so it
hands
out bogus IP info to these systems making it impossible for them to
communicate on the network. I set up a scope on my DHCP server for a bogus IP
range. I then put in a reservation for a MAC address in that scope and
activate the scope. I go to the machine
with that MAC address and release the address, delete its lease from the
server and renew its lease. It comes back with a lease from the good IP range
instead of the bogus one. Is there something I can do to make this procedure
work or am I just out of luck?
Thanks for your help.
Curt
