DHCP Client Option Configuration

Updated: December 11, 2007

Applies To: Windows Server 2008

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

You can configure options for an entire server, a scope, or for a single reserved client. If the server does not recognize the options sent by the client, it ignores the options.


Event ID Source Message



The DHCP service received the unknown option %1, with a length of %2. The raw option data is given below.
