If I run ping www.google.com in Windows 10 on a particular computer, it says Ping request could not find host www.google.com. Please check the name and try again.

If I run ipconfig /flushdns and try it again right afterwards, it resolves the IP as expected and works as do other DNS lookups for a brief period of time.

I tried disabling the "DNS Client" Windows service but that didn't solve it (though restarting the service has the same effect as the above of things temporarily working).

I tried the network diagnostic tool as well as doing a full "network reset" via the windows settings screen.

Some possible items of note are

1. another computer connected to this network works fine
2. things used to be fine on this computer on this network and then they stopped working
3. pretty sure this computer works on another wifi network
4. running sfc /scannow doesn't detect any integrity violations

Here is some debugging output on the network that has the issue while it's occurring:
