Re: 207.46.x.x in FWLog...

Hi William,

Have you tried to do netstat -an on each work station in question?
And have you tried to ipconfig /displaydns or /flushdns on those work
stations?
Then, I would also go and get spybot.  Its free but I liked it so I
donated
To the cause.

Thank you,

Joseph

Again, I hear you. But if an IP address fails to resolve (I.e. it is no
longer in use), how and why can a workstation decide to make numerous
attempts to talk to that IP Address. My theory is that these internal
workstations are infected with some worm or something that has hardcoded
a range of (previously-used) Microsoft IP Addresses, and now they are
trying to get out of my LAN and talk to that IP (maybe DoS it)

Am I way off?

Hi William,
I understand your concerns, but you're looking at it inside-out. The FW
logs don't (can't) show any traffic that generated an alert for "spoof",
"all port" or "all ip" scans; this will be in the IPext..log and you
must correlate it with the ISA log time difference in mind.

Just because an nslookup fails to return a record is NOT an indication
of IP usage; it's an indication of DNS maintenance habits by the
upstream provider and the subscriber.

Hi Jim

I hear what you are saying, but I still don't have an enormously happy
feeling about those entries. 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...

Thanks

Those are not problem entries; they're normal HTTP traffic through the
Firewall service. the IPEXT..log is the one that will show the problem
packets.

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.
