Has anyone been able to access pfirewall.log? To see deeper into what Vista FW records

I get a blank notepad window with a popup that says "access denied".
================================================== ===============
Additionals: Tested 02-03-07
Vista Firewall Public Profile with extra option ticked "Block All Incoming Connections"

-PCFlank Passed All Tests
-Shields Up Passed All Tests
-Audit My PC Passed All Tests

Were they not designed to be tested under Windows XP Operating Systems?

I still feel vulnerable without my trusted Outpost *How secure is this firewall vs Outpost 4?
