Is there anyway to disable negative DNS caching?

Currently and for several years now, OSX (haven't tried OS11) caches negative DNS entries. That is that if it tries looking up a DNS name and fails, the next time it doesn't even try and just returns a failure to the user.


The user then needs to go to the command line and clear the DNS cache.


Is there a way to disable this?


I'm tired of my users saying a server or online resource is down, when it was just a temporary glitch in their DNS availability. Then I have to walk them through clearing their DNS cache.


Thanks!
