If a DHCP client receives inaccurate information in its network configuration information, such as the wrong NIS domain name, or incorrect router IP address, you must look at the values of options in the macros that are processed by the DHCP server for this client.
Use the following general guidelines to help you determine the source of the inaccurate information.
Look at the macros defined on the server as described in How to View Macros Defined on a DHCP Server (DHCP Manager). Review the information in Order of Macro Processing and determine which macros are processed automatically for this client.
Look at the network table to determine what macro (if any) is assigned to the client's IP address as the configuration macro. See Working With IP Addresses in the DHCP Service (Task Map) for more information.
Take note of any options that occur in more than one macro and make sure that the value you want for an option is set in the last processed macro.
Edit the appropriate macro(s) to assure that the correct value is passed to the client. See Modifying DHCP Macros.
