ipconfig /release ipconfig /renew keeps assigning the same ip address

I have done ipconfig /release and ipconfig renew trying to get a different ip address for one of my computers on our network.  I looked at the lease and the ip address that it keeps giving out is not set to expire until next thursday.  Is there a way to get dhcp to hand out a different ip address for this machine.  I am getting an error that their is a conflict with that particular ip address.

You can do one of the following:

-Set a static IP
-Assign a reservation for that machine in DHCP
-unplug the network cable from the machine, delete the lease, plug back in.

Tell the device that hands out IP's (DHCP server) to give ya a new IP.

Release the IP on your machine.
Release the IP on another machine.
Renew the IP on your machine.
You might get the IP for the other workstation.

Go into DHCP and assign a static IP to your workstation based on MAC address.

Release your IP
Unplug the cable
Wait for 12-24 hours
Plug in the cable
Renew your IP
You might a get a new one
Dont think you can do this until the DHCP lease runs out on the DHCP server.
Give the PC a staic IP somewhere near the top of the range, connect, reboot at least twice, chceck to see if it connects, then change back to DHCP, reboot and if it does not give it a NEW IP, then the server needs to be told to shorten the renewal time, most of our implementations are 24 hours max.  Unless rebooting your server is not an option, rebooting it should release the pool of IP's.  Remember, this problem often exists due to an underlying fault where you have somehow disconnected the PC with out logging out, the server needs a while to know it's not there anymore!!
