=================
As Windows doesn't provide an /etc/resolv.conf, it is not surprising that it didn't find it.

I'll be glad to include a fix for this from someone who uses Windows, but as a non-Windows person, there's no way I can develop a solution.

The real issue in this bug is that the Windows specific name server detection didn't work. According to the Python documentation, the platform value is correct, so still no way to work on this. In version 4.0.0, the behavior will change so that if resolv.conf is missing, DNS will assume that the DNS server is 127.0.0.1. That will change what happens in this situation. No idea if it will help.
