DNS Encounters errors in packets

[kgrinberg]

Hello! I get warning in my Log File, EventId 5504 that states:

The DNS server encountered an invalid domain name in a packet from 128.63.2.53. The packet is rejected.


Obviously IP addresses are different in all warnings. Is this normal or is this something I should worry about?

Thanks.

128.63.2.53 is h.root-servers.net.
If you look in your root hints in dns you will probably find it there.
I think it's one of the root dns servers on the internet.
It is regstered under Verisign.

For some reason your server did not like the domain name that it was given from the root domain server.
