Hello,

On my internal DNS server all request forwarded to google DNS 8.8.8.8, and if i check on the even log there are many event ID 5504 with below message. anyone know how to solve this?

The DNS server encountered an invalid domain name in a packet from 8.8.8.8. The packet will be rejected. The event data contains the DNS packet.

    Might also try 8.8.4.4 and or your ISP public DNS as forwarders.

    How many do you have? Do they all have this problem? Might try standing up a new one for testing.
