Windows Server 2008 R2, Windows Server 2012


Dynamic Host Configuration Protocol (DHCP)






The DNS domain option (option 15) is not configured for one or more scopes.


DHCP IPv4 clients will not be provided with a DNS domain and will not be able to resolve names.


Configure a DNS domain option as a server or scope option using the DHCP MMC.

Dynamic Host Configuration Protocol (DHCP) uses options to pass additional Internet Protocol (IP) settings to DHCP clients on a network. Examples of DHCP options include:

  • The default gateway IP address

  • The Domain Name System (DNS) server IP address

  • The DNS domain name

Membership in the Administrators or DHCP Administrators group is the minimum required to complete this procedure.

To configure DNS server as a scope option or server option

  1. Click Start, point to Administrative Tools and then click DHCP.

  2. In the console tree, expand the applicable DHCP server, expand IPv4, and then right-click Server Options

  3. Click Configure Options, check 015 DNS Domain Name, type the applicable domain name in String value:, and then click OK.
