Our corporate DNS servers are blasting our location with bad DNS packets. The best idea I can come up with is that there may be illegal characters in one or more zone files or some incompatibility between Unix and Windows. Here is the situation; I am running split DNS, our internal DNS is on 2 windows 2000 DC's. I am hosting secondary zones for all of the corporate internal locations (about 50) and primary zones for my own domains. Corporate is running BIND. I am receiving the following errors in my DNS logs every 2 to 3 minutes all day long every day:
Warning - Source: DNS, Category: None, Event 5504
The DNS server encountered an invalid domain name in a packet from <IP Address> The packet is rejected.
The IP address points back to the corporate BIND server.
When presented with this information corporate basicaly said they dont care, does not affect them. Loving eh? So, my only chance to get this fixed is to know exactly what is going on. The error flag is relatively bland and the info at support.ms is pretty thin on this error. What can I do to find out exactly what is going on here so I can begin to stop what is amounting to a DNS flood from my own company? Or is there some configuration on my own end I may be able to change to help?
