Comodo alerts even though it is in the network


Since I am in a safe home network I allowed everything for network connections (at least it was predefined from Comodo). Now everytime I go to Network (via explorer) it alerts ‘System is trying to connect to the Internet

Isn’t it strange? I mean it obviously tries to connect to the network to be accurate to… well of course this IP doesn’t really exists, I wonder what the system tries to do… but whatever, it tries to connect over the port 138 (nbdgram)

If I say allow and remember it, it adds a new policy that allows every UDP / TCP connection… every… well of course it is the system, but I still wonder why the Global rule doesn’t fire.

well, also I am using Windows 8 RTM.
