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

Hi there

I am experiencing a general slowdown of internal network traffic every now
and then, so I thought I would check my FW Logs as anything trying to get
out of my company will be recorded there.

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...

Thanks
William R.
