IP Address profiles?

Thanks in advance for any help on this!

Here's the situation:
-At home, I want to use DHCP on my wireless network.
-At work, I want to IGNORE the DHCP address that the wireless network gives me, and force an IP address. Configuring the router to reserve an IP for my MAC is not an option due to a bloated corporate bureaucracy.

Right now, I have to go into control panel and manually configure the network EVERY DAY and while it's not all THAT much work, it's annoying.

Is there any way to automate the process?

Thanks! NetSetMan seems to do the trick. Unfortunately NetProfiles crashed immediately and won't even open.

Or you can use netsh. That comes with Windows.
