I am getting a 5504 error about 150 times per 24hrs.
Appears to be only doubleclick.net DNS names
bad packets are coming from
216.73.81.10
216.73.85.10
216.73.86.10
216.73.87.10
<<ERROR TEXT>>
The DNS server encountered an invalid domain name in a packet from
216.73.85.10. The packet will be rejected. The event data contains the
DNS packet.

This appears only in my win2k3 DNS event logs. I have a test win2k DNS
server that doesn't see this error.
Seems to have been happening at least 2 weeks.
Could this be related to the Cisco PIX 512byte UDP packet limit?
Any ideas?
