I get the following warning message constantly and I don't
know exactly what it means and what to do about it.

"The DNS server encountered an invalid domain name in a
packet from 192.112.36.4. The packet is rejected"

Thank You
 
You will get this occassionally from DHCP clients, especially VPN clients.
If it's "occassionally", you need not worry. If it's clogging your eventlog,
then that's something else. If "192.112.36.4" is foreign to your network,
the same still applies. Make sure you have the "secure against pollution"
enabled on your DNS server. I think it's already enable, but it doesn't hurt
to double-check.

To add. If you disable, disable in the forwarders tab, not the advanced
options or forwarding will stop working. Not sure disabling root hints is
the answer. It may remove the message, but does not help figure out what
the issue is. Are we sending malformed requests to the root, are we getting
bad packets back? Is it a network device in the middle (i.e. firewall,
router, etc) that has mumbled up the name? I would NetMon to figure out
what is going on.
