Hi All To explain more on the below. We are trying to do a query on MX record for abcd.com.sg. domain to the Authoritative nameserver xxxx.com from my pc. You can see the reply as below. Done this mean that the Authoritative nameserver xxxx.com failure or this PC where I am doing the query is blocking to communicate that local DNS server configured on it.
Please help.

You basically said "Something in DNS failed at a very basic level, but I will remove any information that might provide even a slight clue to determine why." You hide the query and the server. All that can really be said is that your client failed to get a response from the specified server. Is the specified system even running DNS? Is a firewall blocking the query? The response? Is the server yours or someone else's? Is routing allowing bi-directional communication? Is these an outage that is blocking communication? The list of possibilities just goes on and on. If you want help, you have to tell us something more than that it failed. -- R. Kevin Oberman, Network Engineer E-mail: rkober...@gmail.com
