Cris reports that he does the following: 

As a Vista Beta Tester and one of the SBS MVPs I've run up against this as well.
After installing the Firewall Client on your Vista machine, Go to c:\program files\Microsoft Firewall Client 2004.
Right Click FwcMgmt and choose Properties.  Go to Compatibility tab, Choose XP SP2 and run as Administrator

Repeat that with FwcCreds and FwcAgent   Also click the box that says show Settings for all users and select both there as well.
Been working fine for me since well before Beta 2

    Does this only work on 32bit Vista. I am using 64bit and cannot get the firewall client to install!
