Where and how to change the ip of the primary DNS server in Windows Server 2012R2?

Question

Domain Name System

A domain controller running WS2012R2 was raised, which works on two networks,
internal ip 10.10.1.1, external 192.168.0.99
It is necessary that DNS works only on 10.10.1.1
I do ipconfig / all on clients, it gives out two DNS addresses in the following order:
192.168. 0.99
10.10.1.1
Hence a cloud of problems until you hardcode DNS on the client. How can I make the DNS server function only on 10.10.1.1?

Answer 1

First, both addresses belong to a private range. If the client has two DNS server addresses, then you need to correct the DHCP server options.

Answer 2

1. in DHCP, in the server/zone parameters, remove the extra DNS address from the parameters
   
2. in the properties of the DNS server, bind it to the desired addresses
