Regarding your screen shot. While it looks like the settings are independent, on my machine, once I set a static IP the DNS switches to static and the setting is grayed out.danpass wrote:However, in the event that someone chooses to set a static IP address for a Windows computer locally on the device, this setting is independent of the DNS server(s) setting.
So, my choices are: Auto IP/Auto DNS, Auto IP/Manual DNS, Manual IP/Manual DNS. There's no way to do Manual IP/Auto DNS.
Edit: A quick read suggests there is no standard for Static IP/Auto DNS. The Auto DNS is part of the information the computer receives from the DHCP when it gets an IP assignment. There doesn't seem to be a way to get the DNS without that. If you set the Static IP locally, there's no contact with the DHCP to get that information.
