Windows 7: DHCP over Network Bridge not working

DHCP over Network Bridge not working

First off, let me describe my setup. I've wired my house for Cat6 ethernet, 2 ports to every room, all connecting to the same switch, which up-links to my wireless router which acts as my LAN's DHCP server. In my office, I have my desktop, laptop, and a network printer. The desktop and printer have static IPs and take up both available network ports on the wall, so I'd like to have my laptop connect directly to my desktop's second NIC using a crossover cable and have the desktop handle all traffic between the router and my laptop.

I've turned off network sharing on both of my desktop's NICs and bridged the connection. My desktop has a static IP of and my router's IP is (DHCP server's address). I've got a couple of weird things going on when I connect my laptop to my desktop's second NIC via crossover cable:

1. If I set the laptop to use DHCP, it gets the private IP, and thus cannot transmit/receive packets from the desktop.

2. If I set the laptop to use a static IP (e.g., I can successfully ping my desktop's IP address from the laptop. The laptop can also see my desktop's shared folders. However, the laptop cannot see the router ( and thus cannot connect to the internet.

Any ideas? Any help would be greatly appreciated
