NIS 2010 - No Windows Firewall running on Windows 7

Running NIS 2010 17.0.0.136 on a virgin W7 install.  In the NIS settings, I turn its firewall off.  Now, W7 is reporting that there is no firewall running, and the Notification Center warns me of this.  

 

I have been testing various combinations of both the beta NIS 2010 and W7 beta and Release Candidate, and I have never seen this behavior before.   The built-in windows firewall always has taken over when the NIS firewall is turned off.    Now that both NIS and W7 are both out of beta, this no longer functions as expected.
