    Server 2012 Essentials BPA warning of DNS Client not configured.

    I'm using two NICs on two machines, Server and PC. Using DHCP from router to connect to internet and use other NICs for LAN.

    I'm just using the server as a file server nothing else. I created a quick image of my setup.

    Is this something I need to be worried about?

    Will this affect network performance?

    Is there a better way to accomplish this?

    TIA

    If anyone could help, that would be great.

    I added the IPConfig from both systems.

    OK, so I disabled the NIC that provides the internet connection to the server and the issues goes away.

    Is there any way to tell the server to ignore the DNS from the Internet router?

    Hi,

    Thank you for the post.

    "OK, so I disabled the NIC that provides the internet connection to the server and the issues goes away. " - this is normal behavior. you cannot configure gateway/DNS address on both internal and external NIC.

    I took care of the issue by eliminating the second NICs on each system and let my router handle DHCP and DNS.

    All is good now.
