Hi Folks
I'm having problems with what I believe to be intermittent negative responses for a host from DNS servers that we forward external queries to and those negative responses being cached.
Because of the intermittent nature of the problem every time it is reported I have not been able to carry out a query on the downstream DNS servers that has not produced a positive result.
I would like to know if it is possible to see if negative responses for this specific host are being cached on our DNS servers.
Thanks in advance
Kevin
