The end goal here is that I am trying to install an Oracle 10g server on my Windows 7 x64 dev box. I use DHCP, and the Oracle installer is throwing up this warning:

Checking Network Configuration requirements ...
Check complete. The overall result of this check is: Failed <<<<
Problem: The install has detected that the primary IP address of the 
system is DHCP-assigned.
Recommendation: Oracle supports installations on systems with DHCP-assigned IP 
addresses; However, before you can do this, you must configure the Microsoft 
LoopBack Adapter to be the primary network adapter on the system.  See the 
Installation Guide for more details on installing the software on systems 
configured with DHCP.

I have installed the loopback adapter, but I am not sure how to make it the primary network adapter. I see this Microsoft KB article on the subject but it's Windows XP-oriented, and I can't seem to find a comparable one for Windows 7. Some of the options it talks about don't seem to be present in the views of the adapters that I see.

So, how can I make the loopback adapter become the primary adapter?
