This article discusses how to create new user or vendor-class identifications for the Dynamic Host Configuration Protocol (DHCP) service in Windows 2000.
Windows 2000 provides two option classes an administrator can use to manage configuration details for DHCP clients within a particular DHCP scope. These option classes are vendor-defined and user-defined classes.
Vendor-defined classes are used for managing DHCP options assigned to clients identified by vendor type.
User-defined classes are used for managing DHCP options assigned to clients identified by a common need for a similar DHCP options configuration.
After defining an option class, individual scopes must be configured with any class-related options to be provided to clients.
Create a New User or Vendor Option Class
Configure a DHCP Scope with the New Class ID
To Set the Specified DHCP Class ID String for Client ComputersClient computers that connect to a Windows 2000-based DHCP server can use the following command to set the specified DHCP class ID string:
ipconfig /setclassid adapter_name class_idFor example, to configure an adapter called "Local Area Connection" with a user class ID called "myuserclass", type ipconfig /setclassid Local Area Connection myuserclass at a command prompt, and then press ENTER.
This identifies the "Local Area Connection" interface to receive the DHCP options configured for "myuserclass" on the DHCP server.
NOTE: Class IDs in ASCII are case sensitive, and must match the class identifying data entered in the Edit Class dialog box used to create the new user or vendor option class.
