The DNS server encountered an invalid domain name in a packet from 157.56.112.42 RRS feed

  • Question

  • I have just seen that I am getting 20 of these messages an hour, always from the same IP address

    The DNS server encountered an invalid domain name in a packet from 157.56.112.42. The packet will be rejected. The event data contains the DNS packet.

    I am running a small business server with 2008 R2 DC, AD and Exchange Server, we are only a small company so resources are limited, any idea on what is causing the problem or how to go about fixing it, its not an IP address we use.
