Can you include some log snippets that show this traffic? I'm betting that it's "late" return traffic.

What I have found is that there are a multitude of PC's out there (with no apparent commonality) that try to make contact with the following IP Address - 207.46.197.121 Naturally the 207.46.x.x range belongs to Microsoft so my thought is that it may be a symptom of some lingering worm or something, but I'm damned if I can find any more about it. Does anyone have any insight on the worms/viruses/trojans etc that would want to perform some sort of DoS on MS via the abovementioned IP Address? Or am I barking up the wrong tree...
