I am seeing really high numbers of requests for dns.msftncsi.com coming from my router. I know this is the domain used by windows to check connectivity. I have disabled that check in the registry for all my windows machines. I have also powered down all my windows machines and these requests do not stop. So far today these requests have averaged 25 times a minute, at a time we are all sleeping and no one is using the internet. The query log shows these requests coming from my router.
I don’t know if these requests are coming from my router (ASUS RT-AC68W) itself or another device that is using my router as it’s DNS. I have the router configured to provide the Pi as the DNS server to clients. But to also use it as the WAN DNS.
Is there any way I can see what device is causing this? I tried seraching on the internet and I cannot find other devices that use this domain that are not running windows. I have eliminated all those devices. These requests make the dashboard unusable, but do not appear to have any affect on he function of the Pi-Hole.
