I've got snort monitoring a DMZ with a pair of web servers using MS NLB
services, and see a lot of x86 NOOP and similar alerts between the two at
the NLB addresses.  I believe that this is a false positive based on the NLB
traffic, but can anyone confirm/deny, or know what else to look for so that
I can be certain?


Look at the acutal packet data.

If the single packet doesn't make it clear, then snarf more packets from
the session and see what's going on.
