Windows 2012 r2 with multiple NICs, block specific DNS queries sending out from particular nic.

Hello,

I have an Application server running on windows 2012 r2 with multiple NICs. Each NIC has its own primary & secondary DNS servers assigned to the interface. But from one nic I see a lot of unwanted DNS queries sent out to its corresponding DNS server.

I have tried changing the NIC priority to lowest on the server which still did not help in resolving the issue.

My question:
Can I block these DNS queries through windows firewall?

Much appreciate your assistance

    What is the purpose here? Multi-homing will cause no end to grief for active directory DNS

      Hi Dave,
      Thanks for your response.
      The purpose from NIC which is connected closed network keep sending standard DNS queries (i.e., Google & windows update queries).

      Basically, just want to know if there is any way stop sending these queries.

      Rahul
