Windows 10 DNS requests


#1

Hi,

Just wondering if anybody else is seeing a lot of DNS requests going to URLs like: array503-prod.do.dsp.mp.microsoft.com?

I had about 900 requests go out from one Windows 10 machine in a 24 hour period after doing a recent Windows update.

Thanks.

That domain is related to something called DoSvc “Delivery Optimization Service”.
Try disabling it on your windows machine:
[HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\DoSvc]
“Start”=dword:00000004
Or
Type netsh winhttp reset proxy in CMD
Hope this helps
