WOS (Windows Operating System) rule between two PC

Hi to everyone!
I have an ibook and a PC at home both of them are connected to net by an ADSL router.
The ibook has the IP#: and the other one, the PC, has the IP#:
Can someone tell me why every time I log in or log off with the ibook, CFP show me the log showed below?
In case, which kind of rule(s) should I add? Please be detailed because I’m a newbie.

Much appreciate any help!

CFP doesn’t prompt me any kind of alerts, before fire up the WOS block, even if I’m in a Custom Policy Mode.
