invalid domain name

[BJohnson]

I get the following event entries in my event log,
multiple times per day. I have made sure "secure cache
against pollution" is turned on, all IP addresses seem to
come from root servers.. Does anyone have suggestion on
how to fix this issue. I have searched high and low on the
net, but have been unable to come up with a fix... Has
anyone else experienced this?

Event Type: Warning
Event Source: DNS
Event Category: None
Event ID: 5504
Date: 7/25/2003
Time: 7:31:44 AM
User: N/A
Computer: DC2
Description:

packet from 128.63.2.53. The packet is rejected.

You can try a couple things, but depends on your config. Does this have two
NICs? That will cause this if not configured correctly.

Make sure you have a forwarder set to the ISP and not to itself. Also make
sure that none of your machines are configured to use your ISP's DNS
servers.
