If a DHCP client receives inaccurate information in its network configuration information, look at the DHCP server data. You must examine the option values in the macros that the DHCP server processes for this client. Examples of inaccurate information might be the wrong NIS domain name or router IP address.
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. Make sure the value that you want for an option is set in the last processed macro.
Edit the appropriate macro or macros to assure that the correct value is passed to the client. See Modifying DHCP Macros.
