  1. Thanks, this totally solved an “unidentified network” issue I was having with my new laptop.

  2. The DNS client “was” important to preventing DNS poisoning attacks that can sometimes happen in just a few second bursts. I have seen lately where the DNS client itself was being used by comcast to poison just my machines DNS registry and spoof FB to capture passwords. This began to happen on boot-up after I would use the “ipconfg /flushdns”. I have suspected for the last 5 years Akaima patch poisoning and have traced the most likely culprit being DNS MIM insertion. This is very hard to nail down and now almost impossible with the round-robin DNS server configs that not only increased the DNS response time but make tracing actors impossible for everyone but the insiders.

  3. You can also just clear your cache for temp problems or issues.

    Thanks. DNS client service is the first service to disable, it is pure nonsense and moreover gets in the way of HOSTS file activity.
