How to turn Off DNS Caching under Microsoft Windows
If you experience frequent issues with DNS caching under Microsoft Windows, you can disable client-side DNS caching with either of these two commands:
net stop dnscache
sc servername stop dnscache
This will disable DNS caching until the next reboot. To make the change permanent, use the Service Controller tool or the Services tool to set the DNS Client service startup type to Disabled. You can permanently disable DNS Client by following the below steps:
Goto Start and click on Run.
Type Services.msc in the Run command box.
A window listing all the services will popup. Search for a service called DNS Client.
Double click on the listed DNS Client service and click Stop. Similarly, you can restart it by clicking Start.
