Cisco Router - How to force a client dhcp address to release

Greetings!

I had to expand our excluded-address to include 5 more ip's that I don't want given out via DHCP. The problem is client (windows laptop) currently has one of the ip's that I added to the excluded range and I need to free it up.

Here is the code for what I did in case that might help...

no ip dhcp excluded-address 192.168.10.1 192.168.10.15

ip dhcp excluded-address 192.168.10.1 192.168.10.20

#sh ip dhcp binding

IP address Client-ID/ Lease expiration Type

I need to release .20 because it needs assigned via static to another device. How can I do this?

Thanks!

in the command prompt use

ipconfig /release

this will get rid of its current ip then follow up with

ipconfig /renew

this will get the new one. Just did this yesterday, so i hope this does it for you.

Thanks! That's exactly what I needed... no access to the client laptop :(
