Hi William, Have you ran a tracert to those ip address? I would at least try that And then do an nslookup. I use a tool called nmap that works Well I trying to track down various issues.

I have run SpyBot on a few of these PC's and the most common "bugs" it found are Hotbar, Alexa Related & DSO Exploit. There are a lot more but these appear common to most.

I will check the Packet Filter logs and see what I find. Fact remains that an nslookup on any of the 207.46.x.x addresses fails, telling me that the IP's are in any case no longer in use... And that in itself tells me there is something illegitimate about this traffic I am seeing...

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...
