TOPIC


    How can we force Open Transport clients to re-acquire their DHCP (Dynamic Host Configuration Protocol) configuration? We want to be assured that when a change is made on the DHCP server that the change is propagated to the client in a timely fashion. Windows 95 includes the ability to cancel and re-acquire DHCP leases in its WINIPCFG utility and we would like something similar for Macintosh computers.

DISCUSSION


    Open Transport clients release their DHCP address lease whenever the TCP/IP stack becomes inactive. This can be accomplished by:

    * Restarting the Macintosh

    * Select "Make TCP/IP Inactive" in TCP/IP Options of the TCP/IP control
    panel. You must save the changes after closing the TCP/IP control panel
    and wait two minutes for the timers to release the current TCP/IP
    sessions. Then select "Make TCP/IP Active" in the TCP/IP Options of the
    TCP/IP control panel. Once again save the changes after closing the
    TCP/IP control panel.

    NOTE: User Mode in the TCP/IP control panel must be Advanced or
    Administrative. TCP/IP Options button is not available in Basic mode.

    When the TCP/IP stack becomes active again, it contacts the DHCP server for configuration information and will acquire any changes made at the server.
