B> "The DNS Server should never send packets to itself."
B> per the Event Log.
Proxy DNS servers have a front-end, that receives queries from
DNS clients and sends responses to them, and a back-end, that
sends queries to other DNS servers and receives responses from
them. The purpose of the back-end is to obtain the information
necessary in order to service the front end. It makes no sense,
therefore, for the back-end of a proxy DNS server to be talking
to the front-end of that same server. At best, this would simply
be an infinite loop.
