Network location for Xbox resets to public after reboot

I have a very simple setup:

My PC is running Windows 7 and is directly connected (by network cable) to my XBox 360.

I have configured my XBox to automatically start Media Center when it starts up.

The problem however is that everytime I reboot my PC, the network location for the XBox is set to "Public" for which streaming is disabled!

So everytime I want to start Media Center I first have to enable streaming for the Public profile, after which the network location automatically changes to "Work".

Is there a way to permanently enable streaming for the Public profile?

Or else to make Windows 7 recognize the XBox as a Home/Work network everytime?

This guy seems to have the same problem

anyone???

How to change the network type?

In short, I had to set my default gateway on my Win7 PC to the IP address of the machine on the other side of my network cable (Xbox 360 in my case).

Hope this helps someone else!
