Hi,

I am getting frequent event log with ID 5504 on my DC DNS server server. Some unknown IP's are trying to send the packet to my DNS server.

Pls find the event message.

The DNS server encountered an invalid domain name in a packet from 211.166.0.166. The packet will be rejected. The event data contains the DNS packet.

Kindly help me on this issue
