Hi, we have a couple of servers on our network that are sending UDP packets port 137 and 138, NetBIOS, to themselves. The source IP and destination IP is the same and they show up in our IDS as 'impossible ip packets', I'm wondering if you think something on these servers might have been miss configured at one time. They're Windows 2003 servers, one is our PDC and the other is a DHCP server. Thank you for any help you may give.
