Could not flush the DNS Resolver Cache error message


While trying to clear DNS Cache on Windows XP or Vista computer, you might get error “Could not flush the DNS Resolver Cache” instead of successful flushing of DNS cache. We generally get this error when DNS Client service stops working or is disabled. You need to enable this service to resolve the issue.

Enable DNS Client Service

1. Click Start > Run
2. Type services.msc and click OK
3. Double click DNS Client option in the list
4. Set startup type automatic and click Start button
5. Close the settings window


After above steps, run the flush DNS command, you should see successful DNS cache clearance message.
