Configuration

Network interfaces must have configured DNS servers. The interfaces on the adapter do not have any DNS servers configured.

If DNS servers are not configured, the computer cannot resolve names or connect to network resources. Critical operations related to Active Directory Domain Services (AD DS) might also fail.

Before you install AD DS and DNS on the first domain controller server in a new domain, make sure that the IP addresses of two DNS servers are configured in the TCP/IP settings properties so that they can be located reliably.

Configure at least two DNS servers per interface.

We recommend that you configure the computer to use a static IP address and at least two DNS servers. If the DNS server is configured to use DHCP-assigned dynamic addresses, when the DHCP server assigns a new IP address to the DNS server, the DNS clients that are configured to use that DNS server's previous IP address will not be able to resolve the previous IP address and locate the DNS server.

  1. Click Start, click Control Panel, click Network and Internet, click Network and Sharing Center, click Change Adapter settings, double-click the network connection you want to change, and then click Properties.

  2. Click Internet Protocol Version 4 (TCP/IPv4), and then click Properties.

  3. Click Use the following DNS server addresses.

  4. In Preferred DNS server and Alternate DNS server, type the primary and secondary DNS server addresses.

  1. Click Start, click Control Panel, click Network and Internet, click Network and Sharing Center, click Change Adapter settings, double-click the network connection you want to change, and then click Properties.

  2. Click Internet Protocol Version 6 (TCP/IPv6), and then click Properties.

  3. Click Use the following DNS server addresses.

  4. In Preferred DNS server and Alternate DNS server, type the primary and secondary DNS server addresses.
