Q. when you created a new VPN connection with Windows 7, 8, and 8.1 and connected it you were able to resolve DNS names of the remote network.
With Windows 10 this does not work anymore.
I compared the VPN connection/adapter settings of both Win 8.1 and Win 10, they look equal.
Also, the status page of the connected VPN connection lists the remote DNS servers.
I could no compare the IPv4 and IPv6 settings due this problem:
This seems to be IPv6 related.
It keeps using my ISP’s IPv6 DNS server instead of my company’s (IPv4 only) DNS server.
If I disable IPv6 on my LAN network adapter, it starts working.
