DNS caching windows server 2016

Question

This is an odd question, kind of a n00b, but does anybody know if there is a way to cache DNS on my windows 2016 server so that it doesn't check for new dns entires for an extended period of time? For example, I want it to keep all records for a minimum of 8 hours. This would be in the event that a major DNS carrier were to go down I would have all the cached for a minimum time.

Thanks

If the public DNS you're using has become unreliable I'd either REPLACE it with another or you can also ADD multiples to forwarders. As to caching by default the client DNS cache holds for 24 hours.

Answer 3

Not sure what is meant. One option would be to turn off or adjust the scavenging

Answer 4

We had an issue where a DNS provider went down, so we were not longer able to access those public records. I'm not sure how to tune this, but was wondering if the DNS provider were to go down, but we had caching enabled, would some how circumvent the outage. I know this isn't the best idea, but was wondering if anybody had done that.

Thanks

Are you asking about domain DNS or public DNS?
