Usually in the case you are describing, you do this on the client side by reducing either the maxcachettl or the maxnegativecachettl (or both) values in the registry. The key is located in HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\Dnscache\Parameters
They may not be present, in which case you'd need to create them. It's a DWORD value that specifies how long (in seconds) you want the client to cache either a positive cache or a negative one. If you set maxcachettl to 1, then the client will cache NO positive responses. If you set maxnegativecachettl to 0, then the client will cache NO negative responses.
Now, if you do this on the DNS server side, preferably using dnscmd /config /maxcachettl, this config will only apply to the recursive queries done by the DNS server side. This doesn't help you in your case because, apparently, this is a local zone and the lookup does not involve recursiveness.
