Renew DHCP Lease

[Jack H.]

Is there a way to make the "Renew DHCP Lease" button in System
Preferences into a Quicksilver item? I don't like having to navigate
to: Apple Menu --> System Preferences --> Network --> Advanced --> TCP/
IP --> Renew DHCP Lease. I have to do it every time I join my
university's wireless network, so a Quicksilver item would be great.
Thanks for any help!
