Hi,

Do you mean you have only one local DNS Server, or do you mean only one (of many) of your DNS Servers has a high latency?

If you only have the one DNS Server, have you tried changing where it is referring queries to?

Most people have them setup to forward queries to their ISP's DNS Server.  If you have that, maybe try changing it to another public DNS Server that is physically close to you, or, say, Google (8.8.8.8) or CloudFlare (1.1.1.1) for example.

If you have multiple DNS Servers in your network, is there anything different about the one that is exhibiting high latency?  If so, try changing its configuration to exactly match one that is not having the problem.


Does either of those fix the problem?

When using windows AD environment ONLY configure the AD DNS in workstations & other servers.
Adding different DNS server will cause lookup failures for all or some local specific addresses that public DNS server wont ever be able to answer.

Hey Noci,

This i can relate with my configuration.
is there any way to avoid ambiguity without  configuring static entry in system?  
And also want to know why secondary dns not picking up the request on failure of primary?

Is the secondary DNS a slave (known to the master DNS) or another DC?
The DNS servers  (master/slave) should decide if they answer them selves (the know their own domain) for forward the request to else where.
(so declare forwarder DNS servers like 1.1.1.1, 4.4.4.4, 9.9.9.9 etc there.)

Yup
!

its already there. but many time its looking for secondary dns instead of primary. also its unable to look for secondary once primary failed.

Is this causing of improper replication of network configuration?
