Network interfaces should have static IP settings. The interfaces on the adapter have dynamically assigned Internet Protocol version 4 (IPv4) addresses.

Dynamic IP addresses can change, preventing clients from locating server resources.

Before you install Active Directory Domain Services (AD DS) and DNS on the first domain controller server in a new domain, ensure that the IP address of the server is static, meaning it is not assigned by Dynamic Host Configuration Protocol (DHCP). DNS servers must have static addresses to ensure that they can be located reliably.

Configure a static IP address on the interface.

We recommend that you configure the computer to use a static IP address. 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.

To perform this procedure, you must have membership in the local Administrators group, or you must have been delegated the appropriate authority.

  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 IP address, and do one of the following:

    • For a local area connection, in IP address, Subnet mask, and Default gateway, type the IP address, subnet mask, and default gateway addresses.

    • For all other connections, in IP address, type the IP address.

  4. Click Use the following DNS server addresses.

  5. 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 IP address, and do one of the following:

    • For a local area connection, in IP address, Subnet mask, and Default gateway, type the IP address, subnet mask, and default gateway addresses.

    • For all other connections, in IP address, type the IP address.

  4. Click Use the following DNS server addresses.

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