You should configure the DHCP server in such a way that when a IP Device issues an IP address query, the server automatically transmits the IP address and port number of the DLS along with the IP address and address of the DNS and default router to the IP Device. After this process, the IP Device can contact the DLS.

This additional information may be provided by the DHCP server in the form of vendor classes. This method is illustrated below :

The following example explains how to set up a new vendor class, assign options to the class, and define the scope of the new class.

1. In the Windows Start menu, select Start > Programs > Administrative Tools > DHCP.
